Paper Abstract

This paper describes a method of coding image sequences based on global/local motion information. The suggested method initially estimates global motion parameters and local motion vectors. Then segmentation is performed with a hierarchial clustering scheme and a quadtree algorithm in order to divide a processing image into the background and target region. Finally image coding is done by assigning more bits to the target region and less bits to background so that the target region may be reconstructed with high quality. Simulations show that the suggested algorithm performs well especially in the circumstances where background changes and target region is small enough compared with that of background.
