Thanks for your reply.
What parameters do you actually mean? I went through the list of
them<http://www.sk-spell.sk.cx/tesseract-ocr-parameters-in-302-version>,
and the only two I was able to find are *matcher_avg_noise_size* and *
textord_heavy_nr*. I have set *matcher_avg_noise_size=100* with no visual
effect.
And if you can point me to *Opening and Closing - Operators* I will
appreciate. Do you mean that C++ *operator-()* is overridden? Any code
examples about their use?
