文件夹LSB中是空域LSB算法程序，文件夹COX中是Cox算法主要程序，文件夹DCT中是频域加在中频的算法的程序。 步骤：把LSB，COX，DCT三个文件夹考在MATLAB目录下； 运行lsb_embed,programme,dct2_embed_mod即可。其中PSNR.m是计算峰值信噪比程序；attact.m & robust.m是攻击程序。(Content: folder LSB of spatial LSB algorithm program, folder COX Cox algorithm is the main program folder DCT frequency domain is added to the IF algorithm program. Steps: the LSB COX DCT three files folder test in the MATLAB directory run lsb_embed program, dct2_embed_mod can. The which PSNR.m calculate the peak signal to noise ratio procedures attact.m & robust.m exploit.)

matlab与C的混编，处理乘性噪声，建立M次开根号模型，需要调整参数。(written with matlab and C by S. Yun and H. Woo, "A new multiplicative denoising variational model based on m-th root transformation".)

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.
