Abstract

In this paper, an image coding scheme, which can be applied to various kinds of images such as HDTV, digital TV, videophone, and multimedia image is proposed. A technique for an efficient video compression based on characteristics of human visual effects in relation to motion is described. An input image is constructed to multiresolution image by discrete wavelet transform. Data compression is achieved that motion vectors in lower band are utilized to process components in higher band according to the degree of movement. The non-sensitivity parts of the segmented bands are removed according to spatial and directional frequency sensitivity. Compared with the existing methods, which uniformly process all blocks in a band, the quality of the image reconstructed by the proposed method is shown to be superior at the same bit rate.
