One easy way: minimum absolute differences. Rescale each character so it is the same size as a set of templates (contained in slices of a 3-d matrix). Use BSXFUN to subtract the actual image from all of the templates and sum the absolute values of this. The minimum one is the match.

No actually no its like i have few characters in a braille document and i cropped them 1 by 1 and i have a group braille templates which contain english lettes for e.g A(100000) so i have to match them and get the english letter as the output.
