Moving Target Extraction and Image Coding Based on Motion Information

概要

論文の詳細を見る
This paper describes a method of coding image sequences based on global/local motion information. The suggested method initially estimates global motion parameters and segments a target region from a given image. Then we coded background and target region by assigning more bits to the target region and less bits to background in order to reconstruct the target region with high quality. Simulations show that the suggested algorithm has better result than the existing methods, especially in the circumstances where background changes and target region is small enough compared with that of background.
