Zdenko, Quan and Sven, Thanks a lot for your suggestions, I think you nailed the problem, So, I installed the Korean language pack :-) however an archive has only one file - kor.traineddata. It doesn't have kor.unicharset, it causes a problem that during "loading" kor.traineddata, tesseract also depends on kor.unicharset. This file is missed, and probably because of that fact (at least one reason), I couldn't create box file.
I tried to find that file, but without success. What I'm going to do, is to create by myself kor.unicharset. I'll look at eng.unicharset to have some comprehension what is a structure. And of cause I'll change the training set according to the Quan/Sven suggestions. -- Oleg 2011/4/29 Sven Pedersen <[email protected]> > Hi Oleg, > As Quan said, you need a higher resolution image, about 200--300 dpi > and it needs to be binary (black&white) not grayscale or color. > Screenshots are typically only 72 -- 90 dpi.
