高斯滤波

利用opencv高斯混合背景建模，并进行开闭运算滤波， 提取视频监控中的车辆(Using opencv Gaussian mixture background modeling and opening and closing operation filtering to extract vehicles in video surveillance)

zernike亚像素识别算法，matlab实现。(Zernike sub-pixel recognition algorithm, matlab achieve.)

主成分分析的三种方法，一种是自编程序，一种是princomp函数,一种是pcacov函数(Three principal component analysis, one is self-programming, one is princomp function, a function is pcacov)

说明：  my_noise文件是已知信号方差，加入信号噪声，可以加入高斯噪声，淑盐噪声,等其他噪声十分有用 其他两个函数时加入噪声信噪比SNR,但是有一点,这种方法并不准确,不能保证加入噪声信噪比为SNR,实际测试中可以看出,但是可以加入相同的信噪比的噪声(my_noise document is known to signal variance, by adding signal noise, Gaussian noise can be added, suk salt noise, noise, and other very useful function when the other two noise signal to noise ratio SNR, but there is one point, this method is not accurate , can not be guaranteed by adding the noise signal to noise ratio for the SNR, the actual test can be seen, but can join the same noise signal to noise ratio)

基于灰度共生矩阵的图像检索技术。完整的特征提取、特征描述、特征匹配以及结果返回。(GLCM-based image retrieval techniques. A complete feature extraction, feature description, feature matching and the result returned.)

说明：  处理在圆极化入射下的聚焦电场和相位。通过去除掉入射电场，把x,y,z分量的电场合成交叉极化的圆偏振电场，看到更好的聚焦效果(It deals with the focusing electric field and phase under circularly polarized incidence. By removing the incident electric field and synthesizing the X, y, z component electric field into the cross polarized circular polarized electric field, we can see the better focusing effect)

说明：  结构光光平面标定源码，注释详细，求出光平面在相机坐标系中的相对位置。(Structured light plane calibration source code, detailed comments, find the relative position of the light plane in the camera coordinate system.)

UCLA一个博士生Andrea Vedaldi编写的SIFT算法(A doctoral student named Andrea Vedaldi of UCLA wrote this SIFT algorithm code)

利用MATLAB进行数值计算，得出HE模的色散曲线。(The dispersion curve of HE mode is obtained by numerical calculation by MATLAB.)
