说明：  改模块用于实现坐标系的转换，将abc坐标转换为dq坐标系(abc TO dq)

本算法结合小波变换和SVD奇异值变换，实现了水印的嵌入和提取，载体图像的鲁棒性和水印的不可见性，提取出的水印图像的和原水印图像基本一致，抗攻击性强。(The algorithm combines wavelet transform and SVD singular value transformation, achieved watermark embedding and extraction, vector image watermark robustness and invisibility, the extracted watermark image and the original watermark image are basically the same, anti-attack and strong.)

JAKE 模型 ,用于衰落信道的仿真,是双信道的仿真的.(JAKE model for the fading channel simulation, is a two-channel simulation.)

matlab时频分析配套源码第12章的程序，请大家共享(Matlab time-frequency analysis supporting source Chapter 12 procedures, please share)

相关向量机(RVM)的matlab源程序，包含快速算法，内含代码使用说明。 RVM采取是与支持向量机相同的函数形式稀疏概率模型，对未知函数进行预测或分类。 优点： (1) 不仅仅输出预测目标量的点估计值,还可以输出预测值的分布. (2) 使用更少数量的支持向量,从而显著减少输出目标量预测值的计算时间. (3) RVM不需要估计过多的参数. (4) RVM对是否满足Mercer 定理的核函数没有限制,适应性更好(Relevance Vector Machine (RVM) of the matlab source code, including fast algorithm that contains code for use. RVM support vector machine is taken the same functional form sparse probabilistic model to predict the unknown function or classification. Advantages: (1) is not only the amount of output predicted target point estimates, but also the distribution of predicted values ​ ​ can be output. (2) using a smaller number of support vectors, thereby significantly reducing the output target amount predicted value calculation time. (3) RVM does not require excessive parameter estimation. (4) RVM meets Mercer theorem on the kernel function is not limited, and better adaptability)

主要是对图像实现DFT,DCT变换，利用二维小波分析对图像作二层小波分解，显示条状图，十字图及频谱等(Realize the image is mainly DFT, DCT transform, the use of two-dimensional wavelet analysis of images for the second floor of wavelet decomposition, indicating strip maps, charts and cross spectrum)
