k-均值算法 做的图象分割实例 （将图片像素聚成三类）(k-means algorithm to do the image segmentation example (poly-pixel pictures into three categories))

基于Retinex的MSRCR图像增强算法的源代码，已经测试，可以直接使用。(Based on the Retinex MSRCR image enhancement algorithm of source code, have been tested, can use directly )

说明：  使用unet对图像进行分割的源码，里面有训练集，可以根据自己的需要更换训练数据。(Use the source code of the image segmentation using UNET, which has a training set, you can change the training data according to your own needs.)

通过阈值去噪，最关键的就是要确定最佳阈值T 的大小.如果阈值太小，可以保留更多的小波系数，但同时噪声也被保留；相反，阈值太大，可以消除更多的噪声，但重要图像特征又将被滤掉，引起偏差.目前使用的阈值分为全局阈值和局部阈值.全局阈值对各层所有的小波系数或同一层内的小波系数都是统一的；局部阈值则是根据当前系数周围的局部情况来确定合适的阈值，具有灵活性.(Threshold denoising, the most critical is to determine the optimal threshold T s size. If the threshold is too small, you can retain more of the wavelet coefficients, but the noise was retained the contrary, the threshold is too large, can be eliminatedmore noise, but the important image features in turn be filtered out, causing bias current threshold is divided into a global threshold and local threshold. global Threshold the wavelet coefficients of all the wavelet coefficients of the layers or on the same floorare unity local threshold is based on the local situation of the current coefficient around to determine the appropriate threshold, with flexibility.)

国外网上找的自适应阈值分割的源程序，测试过，好用。 可以下载(abroad to find online adaptive thresholding segmentation of the source, tested and ease of use. Can be downloaded s)

二值化图像,提取图像中的圆形，例如提取照片中的车轮(Extracting a circular image, for example, extraction wheel photo)

bgslibrary_x86_v1.9.2,是MFC的实现文件，包含37种背景减除算法，对于做目标提取的研究非常有用。(The BGSLibrary was developed by Andrews Sobral and provides an easy-to-use C++ framework based on OpenCV to perform background subtraction (BGS) in videos. )

第27章 透明位图背景上的滚动字幕实例该程序可以方便实现字幕的滚动效果，程序简单易懂(transparent bitmap on the background of rolling subtitles examples of the procedures to facilitate the achievement of subtitles rolling results, procedures simplified)

说明：  用曲波变换点边缘检测实现自动恢复受天气影响的图像(Qu Bo transformation point with edge detection for automatic restoration of images affected by the adverse weather)

用于将视频文件转换成帧图像、帧图像转换为mat语言等(Converts a video file to a frame image, then converts it into a number matrix and the inverse process)
