摘　　要：随着图像信息的大量存储和传输,图像压缩技术的研究越来越深入。分析现有的无损图像压缩技术——基于统计概率方法、基于字典编码方法和预测编码方法。并详细介绍有序二叉决策图OBDD,并对其进行新型和有效的编码,同时分析有损图像压缩技术,并对无损压缩算法和有损压缩算法进行比较。With the large number of image storage and transmission, more and more image compression technology is proposed. Analyses the exist- ing lossless image compression technology based on statistical probability method, dictionary coding method and prediction coding method. And introduces the order two forks decision graph OBDD, and makes a new and effective coding method for it. Simultaneous analyses image compression technology, and compares the algorithm of lossless compression and compression algorithms.
