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.

将信号映射到小波域，根据噪声和噪声的小波系数在不同尺度上具有不同的性质和机理，对含噪信号的小波系数进行处理。实质是减少剔除噪声产生的小波系数，最大限度的保留真实信号的系数。 (Will be mapped to the signal wavelet domain, according to noise and noise of wavelet coefficients in different scales with different properties and mechanism of signal with noise of wavelet coefficients for processing.Essence is to reduce the noise out of wavelet coefficients, the maximum keep the coefficient of true signals. )
