For iSpell dictionaries the option ALLOW_COMPOUND_WORDS is set as default. So the initialization parameter ISPELL_ALLOW_COMPOUND_WORDS could be deleted. Now with a new parameter RESPELL_ALLOW_COMPOUND_WORDS the setting can be changed in the data structure ReSpellParm under 'respell_config'.

15-April-2008
The Kadmos library version now is also available for Windows 64 bit.

12-Mar-2008
Change to Microsoft compiler MSVC 8.0. As this compiler doesn't support single threaded compilation any more, the libraries *_st.lib aren't provided any more. Strict use of the new, save string functions str???_s() and wcs???_s(). For downward compatibility a source strxxx_s.c is provided, which emulates the used new functions as well as ftol2().

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.

Rare nonsense error message in rel_do() "Inconsistent component position".

The characters 5a and 6a (OCRA 5 and 6) are now seperately treated in the classifiers jumbo*.rec, ttf*.rec, and numplus*.rec to get better discrimination of 5 and 6 (machine print).

Improved memory handling in rep_do() and rel_do().

17-05-2004
Local improvements in line segmentation, especially for bold, connected machine print.

Improved memory handling for huge images.

Changed (simplified) function rel_lineshadow(). The returned area now has the data type "unsigned char", the related shadow positions refer directly to the colums of the given image. Thus the macro SHADOW_OFFSET has lost its meaning and has been canceled.

08-04-2004
For the specification of labels now always also the ersatz representation is usable.

Together with the program chopper.exe now additionally the programs Alcstrip.exe and Alcfill.exe are shipped.

Error (RE_PARAMETERERROR) in preprocessing empty images with rep_do().

11-Mar-2004
For file name input with console applications (Chopper, Info, Alcstrip, Alcfill, ...) under Windows the File Open Dialog Box can be used. Therefore either the F1 key has to be pressed in the related menu line, or a mouse click on the prompt text of this line has to be performed. 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'.

The code pages in kadmos.h are enumerated differently.

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.

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
To 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).

12-Feb-2004
Nonsense error message in chopper.exe: 'No classifiers available for the selected labels ...', though the reported labels weren't selected.

06-Feb-2004
Sporadic Protection Error with grid detection in empty images.

23-Jan-2004
Error in re_readimagefile() with reading files *.ras.

20-Jan-2004
The effect of the parameter PREP_SCALING has been extended to images with no specified resolution. If the parameter is set and no resolution is specified (xresolution==0 or yresolution==0), then the provided images are scaled in rel_do() or rec_do() as follows:
- For pure hand print classifiers to a line number of 64 pixels,
- for mixed classifiers hand- and machine print to a line number of 48 pixels,
- for pure machine print classifiers to a line number of 32 pixels.

Memory problems with multiple (10000++) calls of re_hbitmap2image().

06-Jan-2004

Error in reading gray TIFF images.

Double allocation in re_clipboard2image(), resulting in inclomplete free memory with re_freeimage().

Incorrect coordinates and projections with spot removal.

Error in line tracking of rel_do().

Error in allocation of images of the type IMGTYPE_POINTERARRAY in the function re_cloneimage(). As result those images were not freed correctly by re_freeimage(). +- Corrections in alternative segmentation in rel_do().

Corrections in alternative segmentation in rel_do().

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.

16-Sep-2003
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.

Improved classifier mark.rec.

18-Jun-2003
Extremly long computation times in rep_do() with line detection in large images.

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.

The 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

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.

22-Apr-2003
The 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.

02-Apr-2003
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().

In some cases the function re_createimage() didn't provide enough memory.

Protection Error in rare cases, if rel_result_maxlen had been set not big enough.

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.

Endless loop in sichten.exe, if the last screen was filled completely and 'next page' was activated.

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()).

New C++ sample program reldemopp.cpp.

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().

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.

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)

Additional reject labels for critical applications (#-#/#<#=#>#?#S#[#\#]#y#~). A description of the related character shapes is provided in our website.

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.

03-Dec-2002
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.)

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.

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:

Visual Basic and Delphi interface bug fixes (missing parameter, missing function, structure change).

Several minor bugs fixed (multiple images) and improved error handling in the image I/O module.

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.

The developer kit contains an example (cppdemo.cpp) how to integrate Kadmos in C++ programs.

Changes in kadmos.ini ("savebmp"->"saveimg") because of Pen Computing support.

Implementation 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'.

16-Jul-2002

0x0165,0x002C -> 0x0165,0x0032

11-Jun-2002
Functions rep_group_labels() and repr_group_labels() were added. They convert the results of rep_do() from basic labels to group labels.

Accidencial crashes during text output when obsolete files Kadmos.de, Kadmos.hu, or Kadmos.uk where used.

Automatic detection, default setting and evaluation of the code pages CODE_PAGE_858, CODE_PAGE_1251, CODE_PAGE_1253 was not yet fully implemented. For the non-Windows-systems this also concerns the code pages CODE_ISO_8859_7 and CODE_ISO_8859_9.

Adaption of the second Unicode label of the characters LATIN CAPITAL L WITH CARON ("L,") and LATIN SMALL L WITH CARON ("l,") to the usual coding:

OPTIONS_FAST added in kadmos.h If set, this option forces faster recognition for handprint classifiers (hand*.rec from 100% to 60%, Jumbo*.rec from 100% to 50%). Quality is a bit lower, as some rec_values are unjustified lower than without this option, But all alternative results are maintained, noise will more often be recognized as a character.
