  • With grid detection in rel_do(), the value of rel_grid_len had not been returned correctly.
  • New parameters OPTIONS_FAST_REC and OPTIONS_FAST_GRID. OPTIONS_FAST_REC replaces the old parameter OPTIONS_FAST. OPTIONS_FAST_GRID activates a faster grid detection with almost same results. OPTIONS_FAST_GRID can also set with re_layout() as well as new parameter with re_page().
  • New function rel_rec_accent_set(). It works like rel_recset(), but with results of rec_accent().
Up to now Kadmos supported recognition of single characters, lines, and paragraphs. Now the recognition of almost any documents is supported. For this a new function re_layout() is provided. It looks in documents for text areas and returns their positions as circumscribing rectangles. With the more comprehensive function re_page() the text areas can assigned classifiers, with which automatically recognition of those text areas is performed.
Kadmos is applied extensively for reading the coding lines of ID cards and passports. One common problem here is image preprocessing and finding the coding lines themselves. For this applications a special function rep_idcard() is provided. It delivers the results of recognition the same way as rep_do() if it gets applied directly on the coding lines. rep_idcard() additionally also is available as exe file or binary which can be called directly from the command line: "idcard image_file classifier".
As output an XML file with the name of the image_file is generated.
To improve recognition accuracy on images with noisy background a new technology has been implemented. If the parameter OPTIONS_REL_REC_REPEAT is set, badly recognized single characters are read again directly from the original gray or color image. Then they are binarized again with changed parameters, dependent on their measured stroke width.
Now the output of the results as XML file is implemented. For this only the parameter TEXT_FORMAT_XML has to be set with the functions re?_textline(). This also holds for the new functions rep_text() and page_text() which enable the text output of the results of rep_do() and re_page(). The functions re?_textline(), rep_textline(), and page_text() now return short or long spaces with one blank only. The old solution - to return the estimated number of blanks - was dependent on the blank width of the output font, which is not known at time of recognition.
The estimated number of blanks is still returned in RelGraph.leading_blanks, except of the beginning of the line.
The old define CODE_UNICODE has been replaced by CODE_UTF_16. This avoids misunderstandings between Microsofts Unicode (wchar_t as unsigned short) and Linux (wchar_t as unsigned int). The newly implemented CODE_UTF_32 denotes the 32 bit Unicode.
With MSVC no libraries with the compiler switch /Md (multithreaded dll) are provided any more. In the past they have lead to problems several times, especially when the applications should run under new Windows versions. Concerned are libraries like rec_md.lib or rel_md.lib, those that have the ending _md in their filename.

  • New parameter TYPO_EXTENDED_SEGMENTATION. If set with ReParm.typograph, segmentation errors especially with machine print are reduced by about 10%. Of cause this takes CPU time.
  • Now also BMP files with 32 bits per pixel can be processed.
  • Further improved box detection. In rel_do() all noise above and below boxes gets removed. If the parameter OPTIONS_REL_CLEAN is set, additionally all characters and all noise outside the boxes gets removed.

  • Code optimization in rel_do() and rep_do(). Now "normal" text images are recognized with double speed. The optimization was a cooperation of re Recognition Switzerland and Orbograph Israel.
  • After long time - correction of the sample programs for Visual Basic and C#.
03-Feb-2014
  • New parameter OPTIONS_REL_REC_REPEAT for color and gray images. After a first recognition cycle in rel_do() or rep_do() the recognized single characters get binarised and recognized anew directly from the color or gray image. The result is improved recognition accuracy.
31-Jan-2014
  • Bug in re_parmcopy(). In some cases the content of parm->labels did not get copied.
06-Jan-2014
  • Improved line tracking in rel_do()(base line, ...).
  • New parameter OPTIONS_REL_CLEAR. It supports recognition of norm fonts like CMC7 or E13b. In those cases, line images often contain noise in the beginning or in the end part. This noise will be recognized as everything else. But if it is recognized as noise, it will be ommited in the resulting RelGraph and RelResult.
  • Selective improvement of the classifiers Norm.rec (E13b) and Jumbo.rec ($ sign machine print).
  • Error in processing low resolution images with the parameter PREP_SCALING.
  • Corrected and improved version of Rec_Linker.exe. Some classifiers were written incompletely into the generated REC file. Formerly splitted basic classifiers now are combined again.
13-Nov-2013
  • If the parameter "deskew_min" had been specified and the given image had been deskewed, then incorrect coordinates of the results RelResult and RelGrid had been returned.
  • New parameters "options" in ReInit and "rejects" in ReParm. Attention: The structure ReParm has changed! Now it is possible to read only parts of big classifiers (REC files). This has the same effect as the restriction of classifiers by Chopper.exe and can yield huge reductions of computing time. How to apply: Before the call of re?_init() you have to set ReInit.options to OPTIONS_RESTRICT_LABELS and you have to set the parameters ReParm.labels_size, ReParm.labels, and ReParm.rejects, the latter to the required labels and rejects. Now the subsequent call of re?_init() only reads the specified part of the classifier into memory, which is needed to recognize these labels and rejects.
  • The parameters of the program Chopper.exe have been extended by one line. Here the name of a parameter file (INI file) can be specified, in which the labels and rejects of the given or generated classifier are written. Those labels can be read with re_readparm() before the call of re?_do() in case of OPTIONS_RESTRICT_LABELS.
  • New program Multi.exe in the Chopper family. This program enables batch processing with wildcard specification of programs like Alcstrip.exe, Alcfill.exe, or Chopper.exe.
19-Aug-2013
  • KADMOS available for OSX on Apple computers (32 Bit und 64 Bit).
  • KADMOS now also directly reads classifiers which were compressed with gzip. Other compression/decompression functions can be used, if related decompression functions are provided. Gzip compressed classifiers are about half size, but loading time is double as long.
  • New application rec_linker.exe in the Chopper family. This program can be used to link several rec files into one, for instance ttfus.rec, ttfru.rec, and ttfgr.rec. The resulting rec file is much smaller than a rec file with the same labels generated by Chopper.exe.
  • Further size reduced classifier family ttf_s.rec.
28-Jun-2013
  • KADMOS available for iOS on Apple computers (Mac, iPhone, iPod, ...).
  • KADMOS available for Android with the processors ARM, ARMv7a, and X86.
  • Rare memory allocation error in the 64 bit versions of REP (rep_do()) in function SplitComponentHori().

26-Mar-2013
  • Rare errors when rel.init.rel_graph_maxlen and rel.init.rel_result_maxlen where set to different values.
  • Improved classifiers by completed recomputation for newly integrated characters and labels.
  • Extension of the classifier Thai machine print by several ligatures: 0E2A+0E31 - Aw, 0E2A+0E47 - Bw, 0E2A+0E49 - Cw, 0E2A+0E4A - Ew, 0E28+0E48 - qw.
  • Extended character set for the Norwegian classifiers.
  • New classifiers for Welsh, Serbian, Macedonian, Tagalog.
  • New classifier family ttf_l_??.rec and ttf_s_??.rec for machine print. These classifiers are about 50% smaller (ttf_l) or 75% smaller (ttf_s) and 15% faster without essential loss in accuracy.
  • Significantly improved lines and box removal.
  • Improved function rel_find().
10-Dec-2012
  • The labels "a ", "a2", "a_", "a1", (a normal or as o with vertical stroke right), "g2" and "g1" (g like number 9), "Zw", "zW", "ZW", and "zW" (Z, z with horizontal stroke in the middle) were synchronized with Unicode. For this reason the labels "a " and "a2" as well as "a_" and "a1" had to be exchanged. In the other cases only the Unicode has changed:
    Unicode für 'a2' neu: 0x0251 0x0020  Unicode für 'a1' neu: 0x0251 0x005F
    Unicode für 'a1' neu: 0x0251 0x005F  Unicode für 'g1' neu: 0x0261 0x005F
    Unicode für 'Zw' neu: 0x01B5 0x0020  Unicode für 'zw' neu: 0x01B6 0x0020
    Unicode für 'ZW' neu: 0x01B5 0x005F  Unicode für 'zW' neu: 0x01B6 0x005F
    This change is important only for KADMOS users who explicitly work with basic labels or Unicode.
  • In rare cases only the beginning of a text line has been read.
  • re_collect() didn't work correctly under Windows64 and Linux64.
  • Incorrect error handling in rep_do() under multi-threading.

  • Error in line separation (rep_do()) with nonsense images.
  • KADMOS available for für Android.
  • Significant improvement of machine print recognition through integration of several hundred thousand up to now badly recognized characters.
  • Extended Fraktur (Old German) classifier - Czech accented characters added:
    0x0106 ⇒ ;'   0x0107 ⇒ :'   0x010C ⇒ ;v   0x010D ⇒ :v
    0x011A ⇒ >v   0x011B ⇒ <v   0x0158 ⇒ ?v   0x0159 !v
    0x0160 ⇒ &v   0x0161 ⇒ +v   0x0165 ⇒ @v   0x016E ⇒ }.
    0x016F ⇒ {.   0x01CF ⇒ $v   0x01EE ⇒ ~v   0x01EF ⇒ _v
  • Improved Thai classifiers.
  • Extension of the classifier Thai machine print by several ligatures:
    0E1B+0E31 ⇒ aw   0E1B+0E34 ⇒ cw   0E1B+0E35 ⇒ ew   0E1B+0E47 ⇒ fw
    0E1B+0E49 ⇒ gw   0E1B+0E4B ⇒ iw   0E1B+0E4C ⇒ jw   0E1D+0E31 ⇒ kw
    0E1D+0E35 ⇒ mw   0E1D+0E36 ⇒ nw   0E1F+0E31 ⇒ sw   0E1F+0E34 ⇒ vw
    0E1F+0E4C ⇒ ww   0E35+0E48 ⇒ xw
  • Improved lines removal.
  • In case of lacking access permission for CSIDL_COMMON_APPDATA it is not any more posted "KADMOS is already running on this computer", instead a request to contact the administrator.
  • With multithreading, the re?_do() calls have not any more to come out of the same thread as the preceeding re?_init() calls. But it has to be ensured that simultaneuos calls have separate initialisation by different re?_init() calls.
  • Improved function rel_find().
01-Jul-2012
  • Error in respell_do() with set parameter rel_repeat or rep_repeat. The error message was "Unknown UNICODE ...".
  • Error in the Linux versions with the functions re_openimagefile() and re_wopenimagefile(). The file names were not handled correctly.
  • Bug in error handling in rep_do() under multi threading. One consequence (among others) was a wrong error message "KADMOS is already running on this computer".
  • Sporadic error in spot removal (seg->xpos fehlerhaft or seg->ypos fehlerhaft).
  • In the classifier numpluseu.rec the label 1a was missing (OCR-A one).
  • The OCR-A numbers where incorrectly integrated in the classifiers Jumbo, Ttf, and Numplus - partly as basic labels as part of group labels only.
  • Very rare crash in segmentation of nonsense images.
  • Wrong position of the output values of rel_lineshadow() in case of empty columns at the beginning or end of the image.
  • The labels 0x2609 until 0x2612 (marks) have been added to the classifiers Jumbo.rec, Hand.rec, and Ttf.rec. The second characters of the related Unicode labels have been changed from 'd' to ' '. The second characters of the ersatz representation stayed unchanged ("@d", "_d", and "*d").
  • KADMOS-CL is not maintained any more.
29-Mar-2012
  • Sporadically wrong error message "KADMOS is already running on this computer" by missing thread syncronisation under Windows.
  • Wrong storage of Unicode labels in ANSI parameter files. With parm.code==CODE_UNICODE the labels are stored in UTF-8 in the parameter file and for reading they are also expected in UTF-8 instead of Unicode.
  • Essential improvement of the classifiers by a new "turbo" technology. The improved classification has partly led to an over adaption. So we now have to concentrate on new data collection and integration. For this we need active help from our customers and partners. An essential improvement has been reached with alphanumerical hand print.
20-Jan-2012
  • The function rel_do() didn't return the leading spaces for the first character of the line.
16-Dec-2011
  • The function re_readimage() didn't return the image resolution.
  • First usage of a new classifier computation technology. The new 'turbo' classifiers produce significantly less substitutions. In the next months this technology will be applied to all KADMOS classifiers.
10-Nov-2011
  • rep_do() under multithreading didn't return the RepResult values top and left.
13-Oct-2011
The biggest, but least visible change is the use of 64 bit variables in KADMOS as well as in all programs which are needed for data collection and classifier computation.

The biggest visible changes are:

The use of multi threading by the module REP (rep_do()). The standard version of KADMOS now supports parallel processing with two threads. The new server version of KADMOS supports parallel processing with all available threads. This results in a measurable gain in speed. The server version is sold at a fourfold price compared to the standard version. Both variations can be run with the program Famulus from the developer kit. In the result window the related recognition speed can be retrieved. New parameters GENERAL_REPMULTITHREADING and GENERAL_MULTITHREADING are introduced to activate or deactivate multithreading. This improvement requires the MSVC library wsock32.lib, which now has to be linked to all related applications.

If you, after switching to KADMOS 5.0, get an error message like the following:
"KADMOS is already running on your computer" then you probably haven't ordered enough KADMOS licenses. You should either order an additional licence, or - in case of genuine server mode - switch to a KADMOS server license.

New algorithms for classifier computation and discrimination result in a clear improvement of recognition accuracy.
rec_value, the confidence value of recognition, now has a clear meaning. Basic classifiers (for instance 'A' - 'B') recognize 99% of all related characters from our huge data base with a rec_value below 32. 99.9% have a rec_value below 64, 99.99% a rec_value below 96, and so on. For classifiers with 100 or 150 character classes this relationship holds up in an analog way:
90% have a rec_value below 32, 99% a rec_value below 64, 99.9% a rec_value below 96.
If the reject level is changed by 32 (up or down), then the number of rejects gets lower or higher by a factor of 10. This of course holds only true for the single character recognition REC. With the line recognition REL the rec_values changes due to evaluation of the position of the character in the line, evaluations of the character font in relation to the font of the other characters in the line, and other evaluations. From this relationship of the reject level as the percentage of rejected characters a simple rule can be given: If the percentage of rejected characters at reject_level 64 exceeds 5% or 10%, then a data collection and a retraining of the used classifier is strongly recommended. The program Famulus in the developer kit now contains an additional menu item "Reject rates". After every recognition the related reject rates for the reject levels 32, 64, and 96 can be retrieved. In connection with this change the default value for the parameter parm.reject_limit has been set to 128. Even despite this reduction KADMOS 5.0 generates more alternatives than KADMOS 4.4 with the former value 150. If a comparable behavior of both KADMOS versions is required, reject_limit in KADMOS 5.0 should be set to a value of about 110.

IThe result window from Famulus.exe has ben expanded with the point reject rate.

KADMOS was prepared for a switch to the internal use of Unicode, including our service and classifier computation programs. We want to complete this within the next year to be able to recognize fonts like Tamil, Korean, and others. The value of REC_CHAR_SIZE in kadmos.h has been extended from 8 to 16 bytes to prepare the future use of Unicode 32-bit codes.

Two new functions rel_find() and rel_findg() were provided. rel_find() tries to find a readable text line in a given image. rel_findg() is doing the same, but specialized for gray images, which often are difficult for binarization - like serial numbers on money bills.

For the functions re_(w)readparm(), re_(w)writeparm(), and GetPrivateFileName() the default directory under Windows had to be changed in the case of a missing directory specification. We were forced to do this, as Windows Vista and Windows 7 do not work correctly any more with the former default (Windows directory). The new default now is - as already has been under Linux - the working directory (WorkDir). This default can be changed by setting the new environment variable "kadmos_inifiles" to a different default directory.

In kadmos.h REC_CHAR_SIZE has been expanded from 8 to 16 byte to prepare later use of Unicode 32 bit.

All machine print classifiers (jumbo??.rec, ttf??.rec) have been extended by the double accents Unicode 0x201c and 0x201d with the replacement (ersatz) representations '"[' and '"]' respectively. The Thai machine print classifier was extended by the labels 'T2' and 'U2' (replacement representation). These are special forms of the characters Unicode 0x0e14 and 0x0e15.

28-Aug-2007
The Greek-, Cyrillic-, and Fraktur classifiers are extended by the Latin character set. The classifier Numplus.rec is extended by the Arabic and Farsi numbers (formerly called Arabic Indian numbers). To control recognition of such mixed cases (Latin+Arabic for instance), a new parameter font has been introduced. The macros from ALC_HAND to ALC_MACHINE have been removed and replaced by macros FONT_HAND, FONT_MACHINE, FONT_LATIN to FONT_THAI, and FONT_OCRA to FONT_BRAILLE as values for the new parameter font . This means a splitting of the old parameter alc in two parameters alc and font and the introduction of new fonts FONT_LATIN to FONT_THAI. The name ARABIC_INDIAN has been changed into the more usual name FARSI. The classifier numplusa.rec is renamed into numpluseu.rec and numplusa.rec is renamed into numplusus.rec. For Unicode support to all KADMOS functions with file name parameters new functions with wide character file name parameters are introduced. This new functions are rec_winit(), rel_winit(), rep_winit(), respell_winit(), re_wreadparm2(), re_wwriteparm2(), re_wopenimagefile(), re_wreadimage(), re_wwriteimage() and re_collect_winit(). The functions rec_filetitle(), rel_filetitle(), rep_filetitle() and respell_filetitle() return the file name as wide characters wchar_t when the initialisation had been is made with one of the functions re*_winit(). To support programms under Unicode, the KADMOS error handling also has been extended to handle Unicode. Beside the structure re_ErrorText a new structure re_wErrorText has been introduced, which handles error texts as Unicode strings. The related new functions to handle this are re_wGetErrorText(), re_wSetErrorText(), re_wDisplayErrorText(), re_wSetErrorHandler(), and re_wGetErrorHandler(). Accordingly, there is an additional definition of re_wErrorHandler. Under Windows, with missing drive and directory specification, the functions re_?readparm?() and re_?writeparm?() not longer read or write from or into the Windows directory, but instead they work in the current working directory (as they already do under Linux). So, when functions like GetPrivateProfileString() or WritePrivateProfileString() are used simultaneously, the name of the arameter file has first to be completed by a call to _fullpath(). The data structure ReSpellData has been extended by new elements rel_repeat, rep_repeat, and repr_rect. rel_repeat can be set to the address of the initialized data structure RelData which had been used for recognition of the text line before the call to respell_do(). In this case for all words that were not found in the dictionary respell_do() tries a new recognition with slightly different parameters. The same holds for rep_repeat, when rep_do() had been called called before the calls to respell_do(). In this case before every respell_do() call additionally repr has to be set to the address of the RepResult data structure which holds the recognition result of the related text line. Generally the performance of ReSpell has been considerably improved. Beyond that, a new interface has been provided to use private or OEM spellcheckers directly with KADMOS. Therfore the data structure ReSpellData has been extended by the new elements oem_spell_lookup, oem_codepage, oem_wordchars, and oem_reject_char. How to do this is demonstrated in the new sample program OEMSpellDemo. With a new interface ReSpell has the possibility to connect a private spellchecker to KADMOS. For it in the structure ReSpellData are the new elements oem_spell_lookup, oem_codepage, oem_wordchars and oem_reject_char. The new program HashMaker provides the possibility to extract word lists and affix files from iSpell dictionaries, to extend word lists, to combine word lists, and to integrate them into iSpell dictionaries. It is now quite easy to create iSpell dictionaries from private word lists, given as simple text files.

  • RESPELL now also accepts dictionaries (*.hash) from Ispell version 3.3.
  • RESPELL now also handles segmentation alternatives. This needs a lot of computing time. To controll dictionary-lookup, a new item respell_config is added to the data structure ReSpellData. It can be set to the values RESPELL_FAST_LOOKUP,, RESPELL_NORMAL_LOOKUP, and RESPELL_EXTENSIVE_LOOKUP for extensive dictionary search. Further optimization is under work (computing time, performance).
  • New classifiers jumbo.rec and fraktur.rec. They are smaller by 20% to 25% and deliver less substituions.
  • For better readability, the parameter code is written as decimal instead of hexadecimal from re_writeparm?(). For re_readparm?() both representations are supported.

08-Sep-2005
New classifiers for Fraktur (Old German) are provided. Because ligatures are an important part of Fraktur, a corresponding concept has been developed and implemented. For general machine print two ligatures have been added, "fi" and "fl". The related labels are "<w" (fi) and ">w" (fl). These labels are returned by rec_do() . To convert this into regular text, we have provided a new function code_expand_lig() . The functions re?_textline() call code_expand_lig() internally, in this case no explicit expansion needs to be performed. In addition, all machine- and hand-print classifiers (jumbo*.rec, ttf*.rec, hand*.rec) were extended with the new labels “ and " (0x84 and 0x94 in code page 1252). In the classifier mark.rec the label ".d" (unmarked box with digit inside) has been renamed to "@d". The label ".d" now denotes the dot in the font SEMI (classifiers norm*.rec). New strategies for classifier computations have been developed. All classifiers have now been provided with the corresponding algorithms.
Dictionaries are now connected. Therefore a new include-file respell.h has been provided, as well as the libraries respell_*.lib. With the KADMOS DLL version, the new dictionary functions are included in kadmos.dll. Respell is based on the Open Source implementation Ispell. This way the full universe of ready made Ispell dictionaries can directly be used with KADMOS. The same holds true for the Ispell tools to create customized dictionaries (http://www.gnu.org/software/ispell/ispell.html).

As the use of dictionaries can be configured with parameters, extended functions for parameter settings, writing and reading have been provided:
rel_config2(), rep_config2(), re_writeparm2(), and re_readparm2().
The old functions rel_config(), rep_config(), re_writeparm() and re_readparm() can be used as before. With the universal dictionary support, the use of trigrams makes no sense any more and has completely been cancelled. All related items and parameters have been deleted. The new dictionary functions enable a better selection of the alternative results. Therefore the maximum number of segmentation alternatives can be enlarged, from SEG_ALT=4 (old) to SEG_ALT=8 (new). The two new macros TYPO_4_SEGALTERNATIV and TYPO_8_SEGALTERNATIV ensure compatibility with older KADMOS versions. By setting of TYPO_4_SEGALTERNATIV only a maximum of 4 segmentation alternatives is computed. The default value is TYPO_8_SEGALTERNATIV with a maximum of 8 segmentation alternatives. The data structure RelSpot and all related items have been discontinued.
A new parameter deskew_min controls de-skewing of (the) images into horizontal position before recognition.
The blank-detection with numbers and amounts has been improved.

To activate this functionality, the file filename.dll from the KADMOS developer kit has to be copied into the directory of the related exe file.
04-Mar-2004
  • All hand print classifiers have been improved by integration of new samples. The hand print number '4_' has got an additional basic class '41'. This class contains those numbers 4 that are written like a lightning. An analog extension has been made for the hand print characters 'S_' and 's_' with the new basic classes 'S5' and 's5'.
  • Three new code pages are added:
    - CODE_ASCII, containing 7 bit coding only (thus all ersatz representations).
    - CODE_PAGE_1255 and CODE_ISO_8859_8 in preparation of a Hebrew classifier.
    The special handling of a detected code page 1252 (redirection to ISO-8859-1) has been cancelled.
  • To prepare multi byte representations of characters in Unicode, the size of 'rec_char' for result strings has been enlarged from 4 byte to 8 bytes (REC_CHAR_SIZE). Accordingly, TEXT_FORMAT_KADMOS_2BYTE has been renamed in TEXT_FORMAT_KADMOS_MULTIBYTE.
  • he code pages in kadmos.h are enumerated differently.
  • The item 'labels' in reParm is now defined as pointer and allocated accordingly by re?_init(). Its size is returned in the new item 'labels_size'. 'labels' is freed by re?_end(). REC_LSIZE has been deleted. As parameters now can't be simply copied (overwriting of the pointer 'labels'!), a related copy function has been provided:
      KADMOS_ERROR KADMOS_API re_copyparm(ReParm *source, ReParm *destination);
  • An improved Java sample has been provided for the KADMOS DLL version.
18-Feb-2004
  • o avoid confusions, the parameter 'bufflen' in the functions re?_textline() has been renamed in 'buffsize'. It now describes the size of 'buffer' in bytes (instead of characters formerly).

  • New computation of the classifier mark.rec. The label '.d' (box with imprinted number or dot) is left separated, i.e. it is not anymore considered automatically as 'unmarked'. A reduced classifier mark2.rec is provided for the simpler case of empty unmarked versus marked boxes.
  • Approximately 10% faster recognition due to optimized internal routines.
  • Improved machine print classifiers ttf*.rec, especially for bold print.
  • Fast classifiers *_s.rec available. The need only about 60% of the regular computing time of KADMOS Version 4.0e with only a small loss in recognition accuracy. The macro OPTIONS_FASTCHECK in kadmos.h has been renamed to OPTIONS_FAST, its meaning has been generalized.
  • The *.alc-files and chopper.exe have been extended for the use with customer specific feature classifiers. Therefore new in *.alc-files is the section '[content]' with the entry 'labels'.
  • New function rec_get_features() to get the KADMOS features used for recognition.
25-Sep-2003
  • Improved classifier norm.rec, especially for OCR-A (normocra.rec).
24-Sep-2003
  • Error in raster image collection with Kadmos.ini
16-Sep-2003
  • Improved classifier mark.rec.
  • Extended classifier corner.rec. Additional label BLACK SQUARE (Unicode 0x25a0) in this classifier.
  • Rare protection error in line tracking of rel_do().
  • After grid detection in rep_do() a set hook function rel_hook has not been called.
18-Jun-2003
  • Extremly long computation times in rep_do() with line detection in large images.
  • TIFF files with one image only were not released correctly after reading.
  • Error in binarisation von RGB images in case of images with large white areas.
  • The Famulus has been extended to recognize norm print documents with up to three lines with KADMOS-CL.
16-Jun-2003
  • The parameter 'general' in ReParm has got an additional value GENERAL_LINEPOSITION_ONLY. It effects rep_do() only. If it is set, preprocessing only is performed, no character recognition. The results of rep_do() are delivered as usual, the result structures contain the position of the (else to be recognized) lines only. The same holds for the message rep->hWND_line_message and the hook function rep->rel_hook if provided.
  • he parameter 'prep' in ReParm has got two additional values PREP_RGBTOGRAY_COLORMIN and PREP_RGBTOGRAY_COLORMAX. If PREP_RGBTOGRAY_COLORMIN is set, then with processing of color images the colors are eliminated, only the contained gray part is preserved. If PREP_RGBTOGRAY_COLORMAX is set, then with processing of color images the colors are transformed into gray values, according to the maximum value of the red, green, or blue component of the color.
  • For binarisation (conversion of gray- into black/white images) an adaptive thresholding has been implemented. This ensures that images with varying brightness and normal contrast can be transformed with reasonable results.
  • Famulus got a new window to show the result of preprocessing. Thus the menu item 'Filter' could be removed.
  • The option OPTION_BASICLABELS has been split into the specification with ReParm (labels) OPTION_BASICLABELS_PARM and in the specification with the results (RecResult, RelResult) OPTION_BASICLABELS_RESULT. As before, setting of OPTION_BASICLABELS specifies both.
  • The Kadmos engine now also supports recognition of any objects which are passed as customer defined features. Therefore labeled feature files have to be provided, from with re Recognition will generate a related Rec file. For recognition with rec_do() the feature vectors have to be provided under RecData.image.data. Therefore related values of image.imgtype have been added in kadmos.h:
    #define IMGTYPE_FEATURE 4
    #define IMGTYPE_FEATURE_INT 5
    #define IMGTYPE_FEATURE_UINT 6
    #define IMGTYPE_FEATURE_FLOAT 7
  • Improved algorithms for line extraction in rep_do().
  • New and improved algorithms for line tracking, especially for short words.
  • Update/redesign of the Visual Basic interface. The error handling has adapted to Visual Basic, and the usage of the Visual Basic data type 'String' is supported now. For this the following new functions are provided:
    re_ArrayToString(), re_StringToArray(), ARRAY_TYPE_BYTE, ARRAY_TYPE_WCHAR, re_GetErrorText_bas(), re_SetErrorText_bas(), re_DisplayErrorText_bas(), GetPointer(), FunctionAddress().
  • The evaluation of the slant of characters (recognition of \, |, /) in a rec_do() call was dependend of the mean slant of the characters that were recognized in a preceeding rel_do() call.
  • With Chopper in the menu "Selection of [reject] avoid substitutions" sometimes labels were (wrongly) offered for selection, which (correctly) could not be selected.
  • Error with noise removal. Despite properly set parameters, noise wasn't removed in some cases.
  • The parameter PREP_SCALING had not been evaluated properly in rec_do().
  • Rare Protection Error in rel_do() with noisy images.
07-Apr-1998
  • he menue "Segmentation" in reconfig.dll has been extended to enable parameter setting for parm.line_space.
  • With a new algorithm, computation of slant and italic could be improved. This especially concerns the characters backslash, vertical mark, and slash.
  • The slant information of the backslash ("\_", "\ ") was missing in all classifiers.
  • In rep_do() the WM_USER message REP_LINE_CNT had not been sent any more.
02-Apr-2003
  • In some cases the function re_createimage() didn't provide enough memory.
  • In the 'wintools' directory of the Linux version the files *.al0 and *.al1 were provided without the 'carriage return' character at the line ends.
  • Protection Error in rare cases, if rel_result_maxlen had been set not big enough.
  • Endless loop in sichten.exe, if the last screen was filled completely and 'next page' was activated.
  • New C++ sample program reldemopp.cpp.
  • In the following functions the unchanged parameters got the attribute 'const': re_SetErrorText(), rec_init(), rec_filetitle(), rel_init(), rel_filetitle(), rel_recset(), rep_init(), rep_filetitle(), re_writeparm(), re_writeimagefile(), re_writeimage(), re_image2clipboard(), re_cloneimage(), re_getpixel(), rel_textline(), repr_textline(), rep_textline(), rec_collect_kernel(), rel_collect_kernel(), GetRelGridParm(), SetRelGridParm(), GetRelGrid(), SetRelGrid(), GetRelGraph(), SetRelGraph(), GetRelResult(), SetRelResult(), GetRelSpot(), SetRelSpot(), GetRepResult(), and SetRepResult().
  • The reject label '#~' has been moved to the special signs with Unicode 0x224B,0x0020 (TRIPPLE TILDE machine print) and the ersatz representation '~4'. This concerns the classifiers jumbo.rec, ttf.rec, and numplus*.rec.
  • The linking of the Kadmos libraries with Microsoft VC6 was impossible, as the VC7 compiler generated a call to a unknown function ftol2(). Such a function is now provided (as a call to ftol()).
  • To avoid collisions using open-source-software to read and write images, the related KADMOS functions have been placed into a separate library reimageio.lib. This concerns the KADMOS library versions only, and here the functions re_openimagefile(), re_readimagefile(), re_writeimagefile(), re_closeimagefile(), re_readimage(), and re_writeimage(). The function re_freeimage() is contained in reimageio.lib as well as in the libraries rec*.lb, rel*.lib, and rep*.lib.
27-Feb-2003
  • Gray value TIFF images with the specification PHOTOMETRIC_MINISBLACK instead of PHOTOMETRIC_GRAYMINISBLACK were invertedly represented.
  • Rare error "out_img→img_height<=0" with noisy images in rel_do() and rep_do().
  • In some cases memory leak in re_writeimage().
  • Swapped coordinates with detected vertical lines (GRID_LINE_V): left⇒top, width⇒height.
  • Sporadic protection error with mixed font (Jumbo*.rec, Numplus*.rec).
  • Additional function re_image2hbitmap() provided.
  • KADMOS developer kit for Windows now generated with Microsoft .NET. Several compiler errors were found (optimization/string handling) and programmed around. So we recommend profound tests with this version.
14-Jan-2003
  • New feature extraction with improved recognition accuracy. It combines the angle-intersect-analysis with the proven 'mesh'-method (former AEG engine). Despite the much higher computational burden it is only 10% to 30% slower than Kadmos 3.5.
  • Additional fast and small classifiers (Jumbos_s_*.rec, Ttf_s_*.rec, Hand_s_*.rec, ...) for time- or memory critical recognition tasks (pen computing). Speed and accuracy of these classifiers are comparable to Kadmos 3.5. Additional accelleration and classifier reduction is under work.
  • Additional labels (Cyrillic, Arabic-Indian numbers).
    Additional special characters (^ ¡ ¢ ¥ § © ® ¿) for hand and machine print.
  • The hand print character E_ has been split into three form classes:
    - E_ (rectangular form)
    - E1 (like C with dash)
    - E7 (like number 3 inverted)
  • The hand print character b_ has been split into two form classes:
    - b_ (straight, simple form)
    - b3 (looped form)
  • The method of KADMOS's heap allocation (parameter GENERAL_HEAP_ALLOC) has proven superior. This method is now hard implemented, the parameter GENERAL_HEAP_ALLOC has been removed.
  • Additional reject labels for critical applications (#-#/#<#=#>#?#S#[#\#]#y#~). A description of the related character shapes is provided in our website.
03-Dec-2002
  • Rare error with spot removal (SPOTREMOVAL) in noisy images.
  • Rare error in segmentation - subsequent rel_do() calls with equal images and parameters delivered different results.
  • Error in binary filtering of images with 1 byte per pixel. This also led to errors in rel_do() for images with 1 bit per pixel.
  • Already from version 3.5s the name 'slope' has been replaced by 'slant', including all derived names. ('slant' has become a general name for the degree of 'italic' or 'tilt' of a character in the past years.)
  • JPEG/PNG image IO routines now handle image resolution.
  • Up to 128 simultaneous calls of re?_init() can be handled (up to now only 32).
29-Oct-2002
  • Error in combined application of heap allocation and hook functions.
  • Error in grid detection in rep_do(). Corrected formula to determine 'rep_memory_size' in the data structure ReInit:
    rep.init.rep_memory_size = MAX_LINE*sizeof(RepResult) + MAX_GRID*sizeof(RelGrid) + MAX_LINE*MAX_CHAR*sizeof(RelGraph) + MAX_LINE*MAX_CHAR*sizeof(RelResult) + MAX_LINE*MAX_SPOT*sizeof(RelSpot);
  • Label '.2' (fat dot machine print) added in classifiers jumbo*.rec, ttf*.rec, and numplus*.rec.
22-Oct-2002
  • Nonsense error message in Unicode translation.
  • Error in evaluating segmentation alternatives.

  • Slightly improved classifiers jumbo*.rec, hand*.rec, ttf*.rec, and numplus*.rec. The character '1a' (OCRA one) has been added to the classifiers jumbo*.rec, ttf*.rec, and numplus*.rec.
03-Sep-2002
  • [Linux]: Anonymous union members are used in kadmos.h. So GNU extensions should be enabled by passing the option "-std='gnu9x'" to the compiler (GCC v3.x).
  • The date entry of all Kadmos sources (*.h, *.c, ...) is handled now by the CVS (Concurrent Versions System). If developer store the Kadmos developer kit also under the CVS, then they should set the CVS option '-ko' during the update of a new Kadmos version. Without the option '-ko', the date of the updating is filled into the sources.
  • Support of recognition of vector images (Pen Computing) with rec_do(), rel_do(), and rep_do(). Therefore introduction of the new data type ReStroke in Kadmos.h. The function re_drawline() is thus not needed any longer and removed from the developer kit.

  • Changes in kadmos.ini ("savebmp"->"saveimg") because of Pen Computing support.
  • mplementation of a parameter/macro GENERAL_HEAP_ALLOC for parm.general. Memory allocation requires approximately 15% of a typical rep_do() call. This can be reduced to approximately 11% under Windows 2000/XP, but to less than 1% under Linux. GENERAL_HEAP_ALLOC is set as default.
  • Slightly improved classifiers jumbo*.rec, hand*.rec, ttf*.rec, and numplus*.rec.
  • New function KADMOS_ERROR KADMOS_API re_writeimagefile(ReFileHandle, ReImage *image) for the output of images in Bmp-, Tiff-, or Ras-files. The function re_openimagefile() therefore had to be extended by one parameter char *mode ("r" for read, "w" for write, "a" for append).
  • The developer kit contains an example (imgconvert.c) how to use the functions re_readimagefile() and re_writeimagefile() to convert image data to different formats. The programs ras2tif.exe and tif2ras.exe were removed from the developer kit.
  • The function re_SetErrorText() has been added to the developer kit, to enable a correct transmission of error messages. A sample usage is shown in imgconvert.c. For unification, the return value of re_ClearError() is redefined to 'void'.

07-Jun-2000
  • re_image() now also reads records of multi tiff files with the specification of the record number (up to now only NEXT_IMAGE was implemented).
  • Protection error fixed from setting an invalid context (for instance CONTEXT_ENGLISH for Numplus.rec).
03-Jun-2000
  • Sichten.exe has been implemented for Windows.
  • Error corrected in evaluation of OPTIONS_EXCLUDE.
  • Error corrected in segmentation of wide characters.
  • As the 16-bit Windows 3.11 is no longer supported, some Windows libraries could be renamed:

  • Computation of more segmentation alternatives.
17-Jan-2000

  • Error fixed in REL at images of image_type 'c' and with more than 128 pixel lines (up to now no recognition results in these cases).
13-Jan-2000
  • Error in RecMaker.exe - the generated ALC files contain no resp. wrong size information (f:f).
3-Jan-2000
  • The improved segmentation (from version 3.4h) has led to heavily enlarged computation time in several cases. With this improvement also the macros TYPO_SEGALTERNATIV1 and TYPO_SEGALTERNATIV2 could be removed.

  • Improvements / corrections at segmentation.
  • Only few classifiers are delivered directly with the KADMOS software (TTF, HAND, NUMPLUS, NORM, MARK resp. JUMBO with CHOPPER). All national classifiers can be generated with RECMAKER.BAT. For every national classifier an *.AL0 file is delivered. If only some national classifiers are needed, simply delete all other *.AL0 files before starting RECMAKER.BAT. The generation of all national classifiers requires about 300 MB memory and some minutes of CPU time.
  • Die Kennungen für den MARK-Klassifikator wurden geändert.
  • The control for alternative segmentation has been refined. TYPO_SEGALTERNATIV1, TYPO_SEGALTERNATIV2 (see manual).

21-May-1999
  • Improvements with line- and box recognition.
  • Error correction in rec_end() in case of several loaded classifiers.
15-May-1999
  • rel_info() and rep_info() didn't react on the setting of OPTIONS_BASICLABELS (rec_info() was ok.)
12-May-1999
  • The coordinates of the line results (rectangles) in the module REP were wrong .
  • Label selection in the modules REL and REP (parm.labels) was without effect in 3.4c.
  • The error handling was extended by two new functions:
    long WINAPI re_SetPrivateData(long private_data);
    long WINAPI re_GetPrivateData(void);
    So every KADMOS module can be given a private identification. In case of error, this identification is given back in the extended structure re_ErrorText (important for parallel execution).
      typedef struct re_ErrorText_tag {
        long ident;
        char program[64];
        char text[512];
        char systext[512];
        long private_data;
      } re_ErrorText;
              
10-May-1999
  • Error in label selection (version 3.4a and 3.4b) corrected. (The error didn't occure if OPTIONS_BASICLABELS has been set.)
27-Jan-1999
In KADMOS 3.4b now - for the first time - the use of several codepages is implemented (Codepages 850, 1250, 1252; ISO-8859-1 and ISO-8859-2). Further codepages can quickly be implemented. reImage.Dll has been integrated in the KADMOS libraries respectively in KADMOS.DLL, i.e. it is no more required. So the related APIs for reading image files and for connecting bitmaps could be simplified - they now work directly with pointers instead of handles.
27-Jan-1999
