摘要

多小波是小波理论的新分支，将传统的单小波拓展到矢量空间。多小波既包括了传统小波的全部优点，同时又克服了单小波的缺陷，将实际应用中十分重要的正交性、对称性、紧支性、光滑性完美地结合在一起，因此多小波在图像处理方面的应用也显示出巨大的潜力。该文在研究了JPEG2000的核心编码技术——EBCOT算法和多小波变换原理的基础上，提出了结合EBCOT算法的多小波图像编码。算法将各种常用的多小波基，结合EBCOT算法，对灰度图像进行压缩编码。实验结果证明基于EBCOT算法的多小波图像编码方法能够对图像进行很好的压缩。

Abstract

Multiwavelet extends traditional scalar wavelet to vector space

and includes all the advantages of the traditional wavelet. Multiwavelet shows the perfect union of symmetry

orthogonally

finitely support and smoothness. As a result

the applications of multiwavelet in image processing have shown great potential. An image coding method of image coding based on EBCOT algorithm and multiwavelet transform was proposed. In this research

a variety of commonlyused multiwavelet bases were used to combine EBCOT algorithm.The experimental result shows that the proposed method is a valuable attempt of image compression.
