im2block(im,a,b)

divide any image into AxB equal sized sub images

Hi dear MATLAB users,

This function lets you divide colored / grayscale / binary images (im) into equal sub images.

When your image dimensions (M and N) are divisible to a and b, your image divides into (M/a by N/b) sub images, otherwise by decreasing M, N or both dimensions, the image become divisible to a and b.

Hope this could be useful for you.
