说明：  lbp特征提取的matlab文件说明：一共有三个m文件，一个是lbp.m, 存放主要的lbp算法，一个是getmapping,用以做算法的辅助函数，一个是lbptest.m,存放着测试代码。这三个文件需要放到同一个文件夹，并在文件夹中添加相应的图片，具体的图片名字见lbptest.m的代码，运行lbptest.m可以查看结果。
(The matlab file of LBP feature extraction shows that there are three m files, one is lbp.m, the main LBP algorithm is stored, the other is getmapping, used as an auxiliary function of the algorithm, the other is lbptest.m, and the test code is stored. These three files need to be put in the same folder and add the corresponding picture in the folder. The specific picture name is seen in the lbptest.m code, and running lbptest.m can see the results.)
