A novel texture-based Automatic Fingerprint Authentication System (AFAS) is proposed. A fingerprint image is preprocessed to enhance the image by Short Time Fourier Transform (STFT) analysis. Then, three sets of invariant moment features, as a kind of texture features, are extracted from three different sizes of Region of Interest (ROI) areas based on the reference point from the enhanced fingerprint image. Each set of invariant moments contain seven invariant moments. Fingerprint verification is realized by Euclidean distance between the two corresponding features of the test fingerprint image and template fingerprint image in the database. -A novel texture-based Automatic Fingerprint Authentication System (AFAS) is proposed.

opencv特征提取和匹配demo，使用visual studio 2013加上opencv 2.4.9实现；来自opencv官网的demo程序，删除了匹配程序，添加打印程序将opencv特征描述符中数据的格式打印出来，结果保存在surfdes文件中，可用记事本或者notepad打开；

利用模板对图像进行增强，主要用于对道路的增强处理，所用模板是适应予道路增强的，当然可以自己根据自己需要进行修改-use templates to enhance the images, mainly for the increase of road, template is used to meet the increasing road course according to their own need for amendment
