Abstract
A soft windowing technique involves the use of a window for vector assisted frame differing, the window being larger than a macroblock of the structure defined over the video picture. The edges of each window taper so that overlapping windows provide the correct pixel weighting at the edges. For a scheme having 16*16 luminance macroblocks and 8*8 chrominance macroblocks, the luminance window is 24*24 and the chrominance window is 12*12.
