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.

有m￥n(m￡100,n￡100)个金币在桌面上排成一个m行n列的金币阵列。每一枚金
币或正面朝上或背面朝上。用数字表示金币状态，0表示金币正面朝上，1 表示背面朝上。
金币阵列游戏的规则是：
（1）每次可将任一行金币翻过来放在原来的位置上；
（2）每次可任选2列，交换这2 列金币的位置。 -￥ m has n (m ￡ 100, n ￡ 100) a gold coin on the desktop line up a row m column n gold arrays. Each gold coin or a positive upward or back up. Gold status with the number of express, 0 gold express positive upward, the back up that one. Gold arrays the rules of the game are: (1) each can be any turn over his gold on the original position (2) each can choose 2, the exchange of two gold coins in this position.
