灰度处理

二值图像连通域分析，和MATLAB中bwlabel函数功能相似(Connected domain analysis of binary image, and bwlabel similar function in MATLAB)

信息检索和自然语言处理中经常会使用这些参数:准确率（Precision）、召回率（Recall）以及综合评价指标（F1-Measure ） (These parameters are often used in information retri and natural language processing (Precision), recall rate (Recall), and comprehensive uation index (F1-Measure). )

基于visual c++平台，相机标定方法中的直接线性变换方法，即DLT方法(Based on visual c++ platform, camera calibration method of direct linear transformation method, namely DLT method)

说明：  基于matlab和simulink的很好的例子(Matlab and Simulink based on the good example)

非常好的程序，能够对视频中移动目标进行跟踪(failed to translate)

说明：  光学现象模拟，包括反射，折射，牛顿环，杨氏双缝干涉等。转自某blog(optical phenomena simulation, including reflection, refraction, Newton Central, Young's double slit interference. Transfers from a blog)

按照最邻近原则把待分类样本点分到各个簇。然后按平均法重新计算各个簇的质心，从而确定新的簇心。一直迭代，直到簇心的移动距离小于某个给定的值。(According to the nearest neighbor principle, the sample points to be classified are divided into clusters. Then the centroid of each cluster is recalculated according to the average method to determine the new cluster center. Iterate until the moving distance of the cluster center is less than a given value)

数字图像处理，K-SVD字典学习方法，信号的稀疏与冗余表示理论，图像压缩，图像去噪(Digital image processing, K-SVD dictionary learning methods, sparse and redundant signal representation theory, image compression, image denoising)

风云3号卫星投影转换工具，envi中使用，很实用。(FY-3 satellite projection conversion tool, very useful)

最佳拼接线方法进行图像拼接，对学习图像拼接很有用处(The best method of splicing line image mosaic, image stitching is useful for learning)
