边缘检测算法的比较，有susan算子，log算子，prewitt算子(Comparison of edge detection algorithm, there is susan operator, log operator, prewitt operator)

利用halcon mfc写了一个模板匹配demo，可以基于形状匹配，形状缩放匹配，灰度匹配对图像进行匹配

对两幅图像进行配准，分别提取两幅图像的surf特征点以及描述子，得到粗匹配结果，然后根据粗匹配结果，采用ransac方法计算基础矩阵，并去除误匹配点，得到较准确匹配结果(Two image registration, surf was extracted from the feature points in two images to get the coarse matching and descriptor, then according to the results, the coarse matching results, using RANSAC method to calculate the fundamental matrix, and eliminate the error matching, gain a more accurate matching results)

舌像的梯度提取，然后进行分水岭分割，最后进行邻近区域合并，得到舌体图像。(tongue-image s watershed segmentation based on its gradient change.)

图像背景提取，Matlab写的，效果还不错。(Image background extraction)

打开一个图像或者视频文件，相应的轮廓检测功能，视频运动物体的跟踪功能(applications on image，tracking objects in the video)

说明：  GVF-SNAKE分割 解决了收敛速度慢、收敛不理想的问题(Image segmentation using GVF Snake)

radarsat1 的成像程序，包括源码，是个很好用那个的算法(radarsat1 imaging procedures, including source code, is a good use of that algorithm)

读取MODIS的HDF文件和ENVI IDL的程序(MODIS ENVI IDL readhdf.pro)

ViBe算法是由Olivier Barnich 和 Marc Van Droogenbroeck在2011年提出的一种背景建模方法。该算法采用邻域像素来创建背景模型，通过比对背景模型和当前输入像素值来检测前景.(ViBe algorithm is a background modeling method proposed by Olivier Barnich and Marc Van Droogenbroeck in 2011. The neighborhood pixels are used to create the background model, and the foreground is detected by comparing the background model and the current input pixel values)
