blockproc() can do that. Or you can use just regular indexing where you specify yourImage(row1:row2, col1:col2) if you specify the rows and columns correctly. E.g.
block1 = yourImage(1:50, 1:50);
block2 = yourImage(10:60, 1:50); % Overlap of 41 pixels vertically.

If your have a function FUN to be applied to each block, you can use
B = nlfilter(A, [M N], FUN)
