job scheduling problem for single machine

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.

A sample code for digital image processing

用matlab编程，程序将PCA算法用于图像中物体轮廓提取，可以看到在轮廓处，特征值会出现剧烈震荡(With matlab programming, program the PCA algorithm is used to extract the outline of objects in the image, you can see in the outline at the eigenvalues ​ ​ will be turbulent)
