中文说明： 各种kalman滤波器的设计，实现了图像的加水印，去噪，加噪声等功能，算法优化非常好，几乎没有循环，经典的灰度共生矩阵纹理计算方法，Gabor小波变换与PCA的人脸识别代码，仿真效率很高的。
English Description：
A variety of Kalman filter design, the realization of the image watermark, denoising, coupled with the function of the noise, algorithm optimization is very good, almost no circulation, classic gray co-occurrence matrix texture calculation method, Gabor wavelet transform and PCA for face recognition code, simulation efficiency is very high.
