This a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious.

经典的代码,好好看看吧。
说实在的,我也很想获取这里的代码。
有点儿私心。
自己传来才能获得别人的,很好的方法。
谢谢管理员。-Classical code, a good look at it. To tell the truth, I also want to access the code here. A bit selfish. Himself came to get other people s, very good way. Thank you administrator.
