Description: 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.
