该压缩包的程序实现对图像的边缘进行检测，并且对图像进行阈值分割。源码全部为自己编写，效果不错。不知道上传matlab的源码能不能开通会员，所有上传的都是自己的代码，虽然有些简单但是都是自己的劳动，刚起步，希望和大家交流。(of the compressed image program to the brink for testing and the right image thresholding segmentation. Source for all the preparation work to be done. Upload Matlab do not know the source can open membership, are all uploaded the code, Although some are simple but their work has just started, and we hope that the exchanges.)
