椭圆拟合，输入中心坐标及椭圆长半轴和短半轴即可画出相应椭圆(ellipse fitting)

在梯度基础上使用加权平均提取指纹方向场然后使用高斯滤波进行平滑处理(Extraction of fingerprint orientation field using weighted average based on gradient)

1.打开左右两张影像2.Harris算法提取同名点3.显示提取同名点（若要进行下一步匹配则不建议显示，这里只是用于查看是否提取出）4.相关系数匹配（只在找出的同名点内匹配）5.LSM最小二乘匹配（先进行粗匹配，再精匹配）(1 Open the left and right images 2.Harris algorithm to extract two tie points 3 shows the extraction of corresponding points (not recommended to proceed to the next match show, here is used to see if extracted) 4. Correlation coefficient matching (just looking match within a point of the same name) 5.LSM least squares matching (rough first match, then fine match))

ENVI制作散点图可以更改背景颜色 可以显示出R方比以前版本更精细(ENVI make a scatter plot can change the background color can show the R side finer than the previous version)

说明：  实现图像分类，可完成对图像的多分类问题，效果较好(Realize image classification, can complete the multi-classification of images, the effect is better)

一个光流算法的matlab源程序，在图像处理、前景检测与跟踪等方面有很多应用，推荐(An optical flow algorithm matlab source code in image processing, the prospects for detection and tracking, etc. There are many applications, the recommendation)

*****将picture内的所有文件拷贝到MATLAB7.1软件下的名为word的子文件夹下********** 1.testpipei_1.m文件为基于灰度的模板匹配代码，仅为单独使用，不具有交互性 2.testpipei_2.m文件为基于灰度的快速模板匹配代码，仅为单独使用，不具有交互性 3.three.m为带有界面的演示程序，包含了上述两种算法，在MATLAB7.1中，在命令窗口下输入 edit three （three文件一定要在work文件夹下）回车后就可以进行使用了。 4.testpipei_1.m和testpipei_2.m的函数使用说明详细见各自的文件内 5.testpipei_1.m,testpiei_2.m,getOrder.m,gettezheng.m都为函数文件 three.m和three.fig共同为演示界面文件。 (Using MATLAB to image matching two images)

该算法为距离-多普勒成像算法，针对场景的多散射点目标录取回波数据，采用匹配滤波的方法实现距离向与方位向的压缩，识别出目标并得到其位置信息。(The algorithm is range Doppler imaging algorithm, aiming at the multi scattering scene target extracting echo data, matched filtering method was used to realize the distance and azimuth compression, identify the target and its location information.)

用c语言编写的数字图像处理程序，图像读取，图像增强，图像复原，傅里叶变换，离散余弦变换都有(With the c language digital image processing, image scanning, image enhancement, image restoration, Fourier transform, discrete cosine transform has)
