My engine uses both methods. For automated training it employs "tesseract.exe" and other training tools. For automatic recognition it uses Tesseract as a statically linked module called via TessBaseAPI.
Using TessBaseAPI is relatively easy, for instance (pseudocode): Init(datapath, language, OcrEngineMode); [ SetPageSegMode(PageSegMode); ] [ SetVariable(name, value); ... ] SetImage(image_bits, image_width, image_height, bits_per_pixel, image_pitch); [ SetRectangle(left, top, width, height); ] ( GetUTF8Text() | Recognize() | other_recognition_procedure() ) copy_result_into_your_application_structures(); End(); As for the tesseract-dev group, they state that "this group is intended for tesseract developers to share information on updates, improvements...". For such questions as yours the present group is suited better, I think. However it seems to me, the dev team posts in the "-dev" group more often. The biggest changes (in my case) were changes in the training data file format (not much of a problem if you have source box/tiff pairs) and mostly incompatible API (baseapi.h). Yet I can witness version 3.0x has more elaborated API, is much more stabile and produces more expected results.
