Asked by syscatch on 2010-01-28

I am a noob in cuneiform, can you please indicate how can I get the degree of confidence for each recognised character from the OCR engine.
I would like to make a patch to export this value in the hocr format.
Thanks

Look at function CED_GetAlternatives() and try to use it in function Static_MakeHTML (rout module, like OneChar). As far as I know, variable named "probability" has no real probabilistic nature - it is a rating from 0 to 255 with unknown probabilistic distribution

Thanks Polevoy Dmitry, that solved my question.

Thanks a lot, this is just what I needed.
By looking at CED_CreateChar in ced/sources/main/wrapper.cpp, I think that value 254 for probability means least probable.
