img-pro3 Process patches of an RGB image based on a black and white control image This script takes inputs N,M,S, and two .png files (of the same height and width) - one RGB and one in black and white This script then takes N patches of MxM size from random locations in the RGB file based on the control file in black and white (the randomness of the locations is limited by the imposed ratio S of center black pixels to center white pixels)
