IMAGE ENCODING SYSTEM BASED UPON BOUNDARY STRENGTH

摘要

In an image encoder and a corresponding decoder, adjacent regions are identified in an image. Coding parameters for the adjacent regions are identified. Selective filtering is performed at the region between the identified adjacent regions. The selective filtering is based upon determining whether at least two of said adjacent regions have an absolute difference (¾V(j, x)-V(k, x)¾; ¾V(j, y)-V(k, y)¾) of said motion vectors of said at least two adjacent regions at least one of greater than or less than a threshold value.
