The resize to 4x4 method is a awesome idea (not that your method isn't great too) but the first is simpler.

@freespace, could you please explain this "computing the Manhattan distance between the 2 images, using corresponding pixels"

@Ambika: treat the colour of each pixel as a vector of length 3, and compute the Manhattan distance between corresponding pixels in the images being compared. That gives you 4 Manhattan distances. How you derive a single measure from that is up to you. The most obvious is to sum them together.
