摘要

本文对基于小波变换的图像编码进行了改进。特别是利用有效的图像边缘扩展，开发了一种高性能的基于显著小波系数的图像编码(SWCBIC)。与原始的基于显著小波系数的方案，即嵌入式零树小波(EZW)编码的性能相比，我们的算法在图像质量上有改善，特别是在高压缩比下。

Improving image coding using significance of wavelet coefficients with an efficient edge extension

This paper presents our efforts on improving wavelet transform based image coding. In particular, by making use of efficient image edge extension, a high performance significant-wavelet-coefficient-based image coding (SWCBIC) is developed. Compared with the performance of original significant-wavelet-coefficient-based scheme, namely embedded zerotree wavelet (EZW) coding, our algorithm shows improvement on image quality, especially at a high compression ratio.
