总结了五中时频分析方法（STFT,Gabor,WVD,PWVD,SPWVD）,并对个别方法进行了对比。每条程序都有详细的说明(Fifth summarized time-frequency analysis method (STFT, Gabor, WVD, PWVD, SPWVD), and the individual methods were compared. Each program has a detailed description)

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.
