| Abstract: | 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. |
