IMAGE_BOUNDARY
Pixel boundary between black and white regions


IMAGE_BOUNDARY is a MATLAB function which tries to determine the pixels that lie on the boundary between the black and white portions of a simple image. The image should only involve two regions, one entirely black and one entirely white.
