摘要
近年来,随着可视电话,会议电视,人机交互和虚拟现实等多媒体技术的发展,促使人们不断探讨图像编码方法。本文分析了传统的四叉树编码过程及其不足之处,为此,提出了一种新的改进方法以实现渐显系统图像的压缩编码,使压缩比有了明显的提高。
Recently with the development of the technology in videophone, meeting- TV, computer- human interaction and virtual reality, image coding methods are continuously researched. This paper analyzes the coding procedure with traditional quadtree and its disadvantages and an enhanced compression eeding is proposed for systematic images and the compression ratio is significantly improved.
