说明：  经典图像处理方法之一的同态滤波算法matlab实现(Matlab implementation of homomorphic filtering algorithm, one of the classical image processing methods)

a file abaut image segmentation

说明：  功用：利用snake算法实现数字图像的边缘检测，图像分割以及特征提取(function : use of snake algorithm for digital image edge detection, image segmentation and feature extraction)

由于前台开发人员经常需要通过RGB值指定各种各样的颜色，而通过这几个图片就可以马上找到某个颜色的RGB值，从而更快地编写网页(Foreground developers often need a variety of colors through RGB values ​ ​ specified by these pictures can immediately find the RGB value of a color, so to write Web pages faster)

二维傅里叶变换相位提取的matlab模拟程序。(Two-dimensional Fourier transform phase extraction matlab simulation program.)

说明：  可以获取连通域的最小外接矩形，然后做些其他处理(You can get the minimum external rectangle of a connected domain,and you can do something else.)

求一个图像的最大内接矩形面积。 步骤： 1.相机标定。首先根据物像关系式求出其中的参数。注意参数求出后要进行参数校验。 2.从背景中分离出目标 3.边缘检测 4.目标形状参数计算。(For an image of the largest inscribed rectangle area. Steps: 1. Camera calibration. First of all object-image relationship in accordance with the parameters obtained. Attention to the parameters obtained after parameter calibration. 2. From the context of isolated target 3. Edge detection 4. Target shape parameters.)

图像匹配，通过选定模板图像和要要匹配的图像，在要匹配的图像中用红色方框标记处匹配的区域。(Image matching, through the selected template image and want to match the image, to match the image using the red mark at the box matches the area.)

说明：  用MATLAB实现不规则图像的面积测量，采用像素灰度值的占比进行实现(Area Measurement of Irregular Images Using MATLAB)

采用SVD方法进行人脸特征提取,希望对大家有用(SVD method using facial feature extraction, in the hope that useful to everybody)
