图像减操作，对图像进行灰度化，腐蚀预处理，之后进行用原图像减去处理后的图像，再对图像进行平滑处理，能有效去除图像背景中的噪声-Subtraction image, the image gray, etching pretreatment, after subtracting the processed image with the original image, and then the image smoothing, can effectively remove noise in the i

高斯滤波，基于OPENCV的内部调用函数，对图像信息进行高斯滤波，去除噪声-Gaussian filtering, call the function inside OPENCV based on image information Gaussian filtering to remove noise

vc6.0实现SRAD算法，即各向异性去斑噪算法，实现对图像的平滑去噪。在去除噪声的同时保持并增强了图像中目标的边缘。-vc6.0 realize SRAD algorithm, namely anisotropic speckle noise algorithm, to achieve image denoising smoothing. Remove the noise, while maintaining and enhancing the edge of the target image

The program is based on VS2010 + OpenCV2.4, used for image noise reduction processing or remove facial wrinkles.The program from the BBN Computer Vision Lab.
