Abstract

To determine whether any of a menu of motion vectors applies to any given pixel, both forwards and backwards assignment operations (64, 66) are undertaken. Each current picture is shifted (50) by each of a plurality of possible motion vectors and compared (52) to a succeeding picture to determine assignment errors for each pixel. The succeeding picture is also shifted by each of a plurality of possible inverse motion vectors and compared to the current picture to determine assignment errors for each pixel. The assignment errors are combined (62) and if either of the assignment errors for a pixel is large, that pixel is flagged "no match".
