摘要: 嵌入式零树小波图像压缩算法使图像压缩编码技术大大前进了一步,文章针对它在效率上的不足,提出了一种结合双正交小波变换的改进的EZW算法。实验结果表明在不提升码率的前提下,提高了编码速度,有利于实时编码。

Abstract: EZW algorithm improves the technology of image compressing coding , this article introduces a new image compression method combined with biorthonormal wavelet transform based on the concept of Zerotree, which can be considered as an improved method of EZW. The experimental results show that the proposed method speeds up the encoding process on the basis of not increasing code bit rate , and it also benefits on real-time coding .
