Hi. I would like to know what are the cropping methods available for image processing[Optical Character Recognition].
And what difference/which is preferred/better i probably would see in the results between using ROI and auto/manual cropping? thanks! :)

That sounds more like an algorithm question than a MATLAB question.

I only know of three cropping methods (imcrop(), extraction, and masking) and they're all more or less similar because you need to have the rows and columns you have to crop at. But I think that's your real question - how to get the rows and columns to crop at. To a question like that, we generally refer people to research the literature to find the best algorithm, then come back here once you have some attempt at coding it up in MATLAB (but don't ask us to explain some paper to you).
