说明：  matlab使用regionprops求面积，找到连通域(Matlab uses regionprops to calculate area and find connected region)

将彩色图像灰度化，使在处理过程中数据处理简单化(gray color image, so that in the course of handling the data processing simplistic)

利用matlab实现Patchwork算法，包括各种处理攻击(Using matlab Patchwork algorithm, including the attack of various treatment)

说明：  我主要做的是图像分割算法的研究，这个是图像分割的程序，主要用神经网络！(I mainly do is to image segmentation algorithm, this is the image segmentation procedure, the main neural network!)

经典复合式指纹细化算法源码，算法步骤为先用快速并行算法遍历，后用OPTA算法遍历，附有注释。(Classic composite fingerprint thinning algorithm source code, for the first step of the algorithm with fast parallel algorithm traversal traversal algorithm after using OPTA, annotated.)

说明：  本程序是用matlab实现的CLBP源码(The source code of CLBP implemented by matlab)

根据paper思想，自己编写的SPIHT编解码。可以处理不同图像大小的小波系数，严格按照paper中的算法编写。细节见说明文档(under the paper thinking, their preparation SPIHT codec. Image can handle different sizes of the wavelet coefficients and strictly according to the paper prepared algorithm. For details, see the documentation)

说明：  给定两张图片，利用ssim来计算两张图片他们之间的ssim相似度(compute ssim between two images)

sift 图像特征提取算法源码，对研究sift算法很有帮助。(The source code of sift image feature extraction algorithm is very helpful to the research of sift algorithm.)

本压缩包有canny算子的源程序代码和测试图片。(The archive has canny operator of the source code and test images.)
