Claim 5:
6. The method of claim 5, wherein converting each pixel block to a respective MV0 block based on the distribution of pixel types comprises:
determining that a first selected pixel block has a non-bimodal distribution such that only or predominantly mid-range pixels are present, and in response, calculating an average MV0 over only mid-range pixels in the first selected pixel block;
determining that a second selected pixel block has a bimodal distribution such that the second selected pixel block includes at least one foreground pixel and at least one background pixel, and in response, calculating an average MV0 over only foreground pixels in the second selected pixel block; and
setting each average MV0 as an MV0 value for the respective MV0 block.
