javasl275课程习题解module1-module3共7道习题的题目以及程序()

可用于matlab 人脸检测，准确率较高。(It can be used in matlab face detection, with higher accuracy.)

典型的LSB水印嵌入和提取算法，它是一个基本的matlab程序，可以帮助初学者入门 (typical LSB embedding and extraction algorithm, which is a basic Matlab procedures, Portal can help beginners)

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)

这是学习CVI关于网络设置方面的一个很有价值的例子(to study how to use cvi)

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!)

聚类有效性指标,比较全，功能比较强大，是学习聚类的好工具(Clustering Validity Indices)

说明：  matlab编写的直线检测算法，能够有效的提取出直线。和matlab自带的hough变换实现的同样的功能(matlab prepared in a straight line detection algorithm can effectively extract the straight line. And the hough transform matlab own to achieve the same function)

说明：  三次样条插值函数，分别是基于二阶导数的和一阶导数实现的(Cubic spline interpolation function)

稀疏表示实现图像融合。改变图像路径能直接应用(Sparse representation for image fusion)
