系统辨识中一个有用的算法：面积法 对传递函数辨识精度高(System Identification Techniques)

Based on Linear Membership

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. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.

这是一个关于HHT变换的matlab源码，把它复制进去matlab就可以直接使用。很实用。(This is a transformation on the HHT matlab source code, copy it into matlab can be used directly.)
