Multi-Layered Image Coding Based on Wavelet and Matching Pursuit Transforms

Proposes a new multi-layered image coding algorithm based on wavelet and matching pursuit transforms.The original image is divided into smooth edge layer and texture layer,and in each layer different compression algorithms are adopted for coding.As a result,the aim of coding whole image can be achieved optimally.Experiments showed that it can capture texture and edge characteristics efficiently and the quality of reconstructed image is better than traditional single wavelet image coding algorithm at low bit rates.
