此代码主要是实现了图像的各种边缘检测与分割，是用matlab编写的，和大家一起分享(This code is mainly to achieve a variety of image edge detection and segmentation is prepared to use matlab, and the community together to share)

说明：  模式识别中边缘直方图特征提取。。。。每张图片可以得到 一个80维的向量(Pattern Recognition Feature Extraction of Edge Histogram. . . . Each picture can get a 80-dimensional vector)

模式分类工具包，内含大量的模式识别算法。可直接放于toolbox文件夹下，建立路径即可。(Pattern classification tool kit, containing a large number of pattern recognition algorithms. Can be put in the toolbox folder directly under the established path.)

基于灰度膨胀的matlab指纹分割程序，效果不错。来自cubs (a good fingerprint segmenting programme,form cubs)
