胞参考映射点映射法，完整的胞映射程序。已经使用duffing验证。(Mapping cell reference point mapping method, a complete cell mapping program. Have used duffing verification.)

mrvm是RVM的改进，可直接用于多分类。不用什么一对一之类的。效率更高更好使。(Mrvm is an improvement of RVM and can be directly applied to multi classification. No need for one to one. Efficiency is better and better.)

利用MATLAB GUI做的三维数据自动绘图程序，安装运行库后可自动运行，实现从EXCEL读取数据并自动绘制三维曲面图的功能(Using three-dimensional data in MATLAB GUI to do automatic drawing program, after installation of runtime to run automatically read data from a EXCEL and automatically draw the three-dimensional surface map features)

说明：  本文在DCT噪声信号模型研究的基础上,提出了一种新的音频水印嵌入位置选择策略和一个应用该策略的自适应音频水印算法. 通过定义DCT系数的噪声敏感度,建立了水印嵌入位置和嵌入水印后的音频信号的听觉感知性之间的关系,根据音频水印的不可听性的要求选择最优的嵌入位置,然后调节水印强度来满足鲁棒性的要求,从而最大程度地保持音频水 印的不可听性和鲁棒性,为解决音频水印嵌入过程中不可听性和鲁棒性之间的矛盾提供了一种策略.(Though m any w orks in the literature agree that w aterm ark should be em bedded in the middle2fre2 quency coefficients or percep tually significant components, how to determ ine the position em bedded has no universal definition. A new em bedding strategy and an algorithm app lying the strategy are p roposed for audio w aterm arking in DCT dom ain based on research of DCT noise m odal.
