Abstract
A subband coder which can be applied to various kinds of images such as HDTV (high-definition television), digital TV, and videophone is proposed using human visual characteristics. Data compression is achieved by the procedure based on human visual characteristics, where motion vectors in lower band are utilized to process components in higher band according to the degree of movement. Since the compression of the signal in higher band is accomplished by motion information, the proposed method shows good performance regardless of the degree of movement. Compared with the existing methods, which uniformly process all subblocks in the same subband, the quality of the image reconstructed by the proposed method is shown to be superior.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
