Abstract

Abstract

An adaptive transform coding method of image is presented, in which an image is devided into a number of image sub-blocks and two-dimensional symmetrie cosine transform is performed. And the bit-allocation map for adaptive quantization of transform coeffieients is obtained through estimation and transmission of some parameters of the sub-blocks. In the paper analytical and simulated experimental results of the method are given.
