(a positive integer power of 2) specifies the minimum dimension

of the quadtree regions (subimages) allowed. If necessary, the

program pads the input image with zeros to the nearest square

size that is an integer power of 2. This guarantees that the

algorithm used in the quadtree decomposition will be able to

split the image down to blocks of size 1-by-1. The result is

cropped back to the original size of the input image.-segments image F by using a
