shree namaste I am trying to OCR the attached image. Getting not so good results. Even for text which is apparently clear. Eg. in the first line, B is recognized as H, under dot for 't' in 'most' 4th line etc. The image has warping but still best/Latin and Google OCR produce better results. Is it possible to add diacritics to Latin? Can you help in any way?
