Description: 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.

Description: 对某些相同灰度级成片连续出现的图像（如洪水图），行程编码也是一种高效的编码方法。特别是对二值图像，效果尤为显著。在一个逐行存储的图像中，具有相同灰度值的一些像素的序列，称为一个行程。-Appear in successive images of some of the same gray level into tablets (such as flood charts), the run length coding is an efficient coding method. In particular, the binary image, the effect is particularly significant. Some of the pixels having the same gray value in the stored image of a progressive sequence, referred to as a stroke.
