Hybrid Coding of Image Sequences by Using Wavelet Transform

Abstract

In this paper, a new method of hybrid coding of image sequences by using wavelet transform is proposed. The basic MPEG scheme with DCT has been modificated in sense of replacement DCT by wavelet transform. In the proposed method, the motion estimation and compensation are used for motion vectors calculation and different frame between current frame and compensated frame is coded by using wavelet transform. Some experimental results of image sequences coding by using a new method are presented.
