Two different ways are shown in the FAQ: http://matlab.wikia.com/wiki/FAQ#How_do_I_split_an_image_into_non-overlapping_blocks.3F. Inside the loop, you can call graythresh() or some other threshold picking algorithm, and im2bw().

If you can, it might be best to just process it in place without chopping up into separate variables or cells. But if you must have different images, then you can stitch them together like this:
tallImage = [topImage; bottomImage];
wideImage = [leftImage, rightImage];
You'll need to change the images as you move along from blobk to block.
