Arithmeticcoding

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.

MATLAB命令大全 挺管用的，具体看看吧，有实体书来着

这个是基于matlab的维纳滤波设计，其中包括两个列子，一个是在时域实现滤波器，一个是在频域实现滤波器，两个列子都是对chirp信号进行处理的(there are two examples for weina filer desined in matlab ,one is achieved in frequency domain and another is achieved in time domain.the two weina filers are desined to remove noise from chirp.)
