This is 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.

蒙特卡罗方法的基本原理及思想如下：
当所要求解的问题是某种事件出现的概率，或者是某个随机变量的期望值时，它们可以通过某种“试验”的方法，得到这种事件出现的频率，或者这个随机变数的平均值，并用它们作为问题的解。( The principle of Monte Carlo method and it s application are int roduced.)
