filter

This program is used to compute the trapdoor channel capacity.

说明：  维纳滤波器经典代码，加了详细标注，更适合阅读和改进。(Wiener filter classic code, add the detailed mark, more suitable for reading and improvement. )

消隐算法 三维 消隐分类 画家算法 算法的介绍及例子说明(Vanishing algorithm 3 d Vanishing classification Painter algorithm The algorithm is introduced and examples )

DWT水印嵌入程序，DWT水印嵌入程序，DWT水印嵌入程序(The DWT watermarking algorithm program)

说明：  对比了dv-hop基本算法，和加入pso后得算法。由于结果是随机产生的，不能保证每次得结构都能提高，但大部分时候，比基本算法得定位准确度好。(DV hop algorithm is compared with PSO algorithm. Because the results are generated randomly, it can not be guaranteed that every time the structure can be improved, but most of the time, the positioning accuracy is better than the basic algorithm.)
