studyMATLAB

利用matlab编写的串行通信助手程序，GUI界面对学通信的应该很有帮助(Matlab serial communication using a helper application written, GUI interface should be helpful in learning to communicate)

PCA,KPCA完整程序，对研究人脸识别非常有用(this the code of pca and kpca)

Project on Image Restoration

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.
