matches, also referred to as modes, to the reference block and compares the
average modes to the reference block and generates errors for each, column 7
lines 6-31. The best mode is then determined by comparing the errors of each
mode to determine which mode has the lowest absolute error, column 7, lines
48-50.
Thus, we find that both Greenfield et al. and Wang et al. teach
determining a best match between a block in a first image and a block in a
second image. Both references teach averaging images as part of the process
of determining a candidate for best match. Both references teach selecting a
candidate based upon either a difference or error between the two images.
However, the references do not produce the best match based upon an average
of all the candidate block, they teach that the best match is selected is one of the
candidates which meets the selection criteria.
