Hi! I want to run a block matching search on two images. How can I choose the block of pixels?

Can you elaborate? Until then I can offer demos of blockproc (attached), normalized cross correlation, and non-linear filtering, and the FAQ: http://matlab.wikia.com/wiki/FAQ#How_do_I_split_an_image_into_non-overlapping_blocks.3F

Actually you probably want to do this in nlfilter since blockproc moves in "jumps" whereas nlfilter moves a pixel at a time, but the basica algorithm is the same.

Hi; I have a same assignment on SSD matching template. I could not follow/understand your earlier answer and code. Can you please create a single Matlab code by considering an example image to carry out SSD matching.
