直接用于进行河流直线基流分割，界面友好，参数修改方便(Directly used for river base flow separation friendly interface)

matlab 图像处理方面的经典书籍，值得初学者仔细认真的学习(matlab image processing aspects of classic books, worthy of serious study carefully beginners)

图像分割方法区域增长法，基于区域增长的感兴趣区域分割方法，区域生长是一种根据事先定义好的准则将像素或者子区域聚合成更大区域的过程(Image segmentation algorithm region growth method)

在matlab中的分形图像放大程序；对初学者很有用哦！(In the matlab source code to raise the image resolution is indeed very useful!)

采用最小均方差法对虹膜瞳孔定位，虹膜外圆定位，归一化及其增强处理，圆拟合(Using least-mean-variance method of positioning the iris pupil, iris outer location, normalized and enhanced handling, circle fitting)

说明：  利用matlab进行编译，显示raw格式的裸数据(Compile with matlab and display raw data in raw format)

1、运动目标进行检测与跟踪，背景差分法，卡尔曼滤波，检测结果用红色外接矩形框表示，跟踪结果用绿色矩形框表示 2、采用平均背景法更新背景图像； 3、代码部分附详细解释(1. The moving target in the video sequence is detected and tracked, the moving target detection part uses the background difference method, the tracking part uses Calman filter, the detection result is represented by the red outer rectangle frame, and the tracking result is expressed in green rectangle frame. 2. The background image is updated with the average background method. 3. The part of the code is explained in detail)

对移动目标检测，需要先用鼠标框定感兴趣的目标，然后才能追踪。(Moving target detection, target mouse framed interested need to use before tracking.)

说明：  该代码能实现图像缩放功能，简单，容易理解(The code to achieve the image zoom feature, simple, easy to understand)

基于轨迹划分的异常轨迹检测方法。首先采用两种分段粒度将每条轨迹分为若干子轨迹线段，然后，在基于距离的异常检测方法的基础上，引入调整系数的概念，采用密度与距离相结合的方法进行异常轨迹检测。 (Abnormal trajectory detection method based on trajectory partition.Firstly each trajectories should be divided into several substrajectories using two granularities. Then the notion of adjustment coefficient is introduced on the basis of distance based anomaly detection method, and the abnormal trajectories are detected combining density and distance. )
