对图像进行高通滤波和低通滤波处理，包括图片和测试程序。(High-pass filter the image and low-pass filter, including pictures and test procedures.)

利用双线性插值，获取亚像素位置的灰度值。适用于得到sift、surf得到的特征点坐标处的灰度值获取(The gray value of sub-pixel position is obtained by bilinear interpolation)

镜片面形数据通过zernike多项式用协方差方法拟合得到的zernike系数(Zernike coefficients covariance fitting)

用于求取灰度图光斑的中心，可以用于寻找光斑图像的中心，如激光光斑，(Used to strike a grayscale facula center spot can be used to find the center of the image, such as the laser spot,)

对两幅图像提取特征点，并计算基本矩阵，对两幅图像进行极线矫正，并画出校正后图像特征点的极线，效果非常好(The two images of the image feature points in the feature points are extracted, and the calculated fundamental matrix, correction of lines of the two images, and after the draw correction lines, very good results)

说明：  求图像峰值信噪比PSNR代码，相信对你很有用(PSNR PSNR for the image code, I believe that is useful to you)

一个简单的图像处理中粗糙度和方向度的MATLAB编程实现，已经通过调试，无误可用(A simple image processing in the direction of roughness and degree of MATLAB programming, has been through debugging, accurate available)

图像拼接源码实现，包括多频率图像融合，sift特征点配准算法(Image Stitching source implementation, including multi-frequency image fusion, sift feature points matching algorithm)

基于暗通道先验的但图像去雾,暗通道先验就是基于这样一个假设：在绝大多数非天空的局部区域里，某一些像素总会有至少一个颜色通道具有很低的值。(Single Image Haze Removal Using Dark Channel Prior.)

用Matlab实现的Canny边缘检测算法，压缩文件中附有一张实验图片(Using Matlab realize the Canny edge detection algorithm, compressed file attached to an experimental image)
