So I have segmented an image consisting of letters, it's a binary image. I have used regionprops and bwconncomp, standard Matlab functions. So now I want to extract features on the region of pixels that are equal to one, into a feature vector. It is also good if the features does not depend on which position the region has, so if the regions is shifted in x or y direction then the same features will be obtained. Is there any Matlab function that can do that? Thank!

It's just a general purpose generic routine. It's not specially adapted for OCR. See http://www.mathworks.com/help/vision/ref/ocr.html#bt548t1-2_1

There is a built-in ocr function in the Computer Vision System Toolbox.
