I am doing OCR for Kannada and English. What are the best features in image? Please also tell me some tools to perform OCR before implementing it as code (like Rapiedminer for machine learning).

Tesseract is an often used OCR tool, but before that you need to pre-processing your image with some basic operations such as binarization, morphological operation, and illumination equalization, and letter extraction.
