摘要

分形编码是一种以图像的自相似性作为冗余的编码方法，近年来得到了广泛的研究。本文提出了一种分形视频编码方法，该方法通过正交变换去除视频序列中沿时间轴的冗余，然后在分形视频编码前根据视频序列的频率分量对编码结果进行重新排列。与传统的分形视频编码相比，在信息量几乎相同的情况下，平均信噪比得到了提高。©2006 Wiley期刊公司电子工程学报，2009,31 (3):357 - 357;在线发表于Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002 / ecjc.20248

Fractal video coding with the orthogonal transformation

Fractal coding, which is coding with the self-similarity of the image as redundancy, has recently been studied extensively. In this paper, a method of fractal video coding is proposed in which the redundancy along the time axis is eliminated from a sequence of videos by the orthogonal transformation and then the results are rearranged according to the frequency components before fractal video coding. In comparison with the conventional fractal video coding, the average PSNR is improved with almost identical information content. © 2006 Wiley Periodicals, Inc.
