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.

Yes and what about the above doesn't do that? You get the index corresponding to the letter (1-26, or 52, or however many) and you keep that letter.

If you're going to use some program to analyze your braille images, then you must already have braille images obviously. Otherwise why would you be interested in a Braille OCR program?
I think you really meant to ask how he took a sheet of braille and found the bounding box of each individual braille character.

yes , you think right
there is a lack in the avialability of Braille character images
