improfile (with the default 'nearest' interpolation) should give you all the pixels between your two points. It's then trivial to sum the pixels that are 0.
numblackpixels = sum(improfile(yourimage, locationofpixel1, locationofpixel2) == 0)

I have absolutely no idea what you are asking now. There's only one direction between two given pixels.
