猫脸变换用于水印中，将水印图像经过一定次数的变换得到不能识别的图像，增强了水印的鲁棒性(Cat face transform for watermarking, the watermark image after a certain number of times the transform of the image does not recognize and enhance the robustness)

实现数字音频信号的幅频均衡，采用了lms算法和rls算法，有MATLAB的simulink模型，和m文件，还有部分c程序，已经本人完全测试过。(Digital audio signal of the amplitude-frequency equalization, using lms algorithm and rls algorithms, there are MATLAB-simulink model, and the m file, as well as part of the c program, I have been completely tested.)
