trifilter

一个基于MFC窗口的具有图形图像处理的功能的MFC程序，可对图像灰度，滤波等处理好功能(MFC program has a function of image processing based on MFC window can be a good feature for grayscale images, filtering and other processing)

几个将图像分块，将分块图像拼接，和裁减图像的实用小程序(several image block to block image mosaic, and the reduction of small images of practical procedures)

用MATLAB实现的边缘提取函数，实现了sobel算子、canny算子，Robert算子、prewitt算子、marr算子(Using MATLAB to achieve the edge detection function, the realization of the sobel operator, canny operator, Robert operator, prewitt operator, marr Operator)

基于最大类间方差准则的阈值分割算法。其基本思想是对像素进行划分，通过划分得到的各类之间的距离达到最大，来确定合适的门限。(Based on the maximum between-cluster variance criteria threshold segmentation algorithm. The basic idea is to divide pixels, obtained through the division of the distance between the various types of maximum, to determine the appropriate threshold.)

说明：  该文件主要用于减少相干斑噪声，包含各种常见的滤波器如Lee滤波器，Frost滤波器等(This file is mainly used to reduce speckle noise, including a variety of common filters, such as Lee filter, frost filter and so on)

链码直线检测，采用求取图像边界，然后边界跟踪，判别直线(Chain code line detection, to strike the image boundary, then the boundary tracking, discriminant linear)

视频水印matlab源码，此为第三个压缩包，在水印领域的爱好者可以下载作为参考(Video Watermarking Matlab source, which is the third-compressed, Watermark in the field of lovers can download as a reference)
