n类PSVm 算法程序，相对于svm运算速度较快(n Class PSVm algorithm procedures, in relation to computing speed svm)

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.)

The code implements the following paper: Guorong Xuan, Jiang Zhu, Jidong Chen, Shi Y.Q., Zhicheng Ni, Wei Su, "Distortionless data hiding based on integer wavelet transform" IET Electronics Letters, Volume: 38, Issue 25, page 1646- 1648, December 2002. (ISSN: 0013-5194) The watermark embedding and extraction modules have been implemented separately. The watermark embedding module embeds the watermark using bitplane compression in the integer wavelet transform domain. The watermark extraction module extracts the previously embedded watermark and restores the original image. A logo image is used as a watermark but can be replaced with any thing.
