1. A video motion estimation method comprising: extracting luminance data from a predicted frame and a reference frame, said predicted frame including a predicted block of predicted pixels, said reference frame including reference blocks of reference pixels, said luminance data associating reference luminance values with each of said reference pixels and predicted luminance values with each of said predicted pixels; bit-wise comparing reference luminance values for each of said reference blocks with respective predicted luminance values; generating match measures for each of said reference blocks as a function of the results of said bit-wise comparing; and determining a motion vector as a function of said match measures.
