Dear Pirrre,
I tested using OCRB.tif and eurotext.tif and its output are attached
herewith. I used commandline for both tif
using tesseract 3.0 version.
It is observed that for output texts using *cst*(generated by you) and *eng
* datafiles for *OCRB.tif *are identical and found to be in order
whereas output texts using *cst* and *eng* datafiles for *eurotext.tif* are
not identical and found that text generated using *cst* has many mispelling
when compared to output txt using *eng*.datafiles viz traineddata..
The above observations are brought to your kind investigation and valuable
guidance regarding how to improve accuracy in the output.
With regards,
-sriranga(77yrsold)
