I'm trying to train the attached files (Tesseract 3.02, following the instructions at http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract3 ) , and although I can compete the training process successfully I can't get tesseract to work with the produce trainneddata file - I always receive the error:
tessdata_manager.SeekToStart(TESSDATA_INTTEMP):Error:Assert failed:in file adaptmatch.cpp, line 555 I have attached the .box, .tif, and font_properties file I used for training purposes. (Although the training instructions says to add .exp? after the font name in the font_properties file, when I use ocr.exp0 as the font name in that file the shape clustering than fails). The following is the process I use for producing the training file: ./tesseract eng.icr.exp0.tif eng.icr.exp0 nobatch box.train.stderr Tesseract Open Source OCR Engine v3.02.02 with Leptonica APPLY_BOXES: Boxes read from boxfile: 315 Found 315 good blobs.
