用opencv实现LBP算法。通过一个3*3的模板在图像矩阵上滑动，用模板四周的八领域像素和中间的像素值比较，大于的为1，小于的为0，从左上角顺时针排列，然后转化为十进制放在模板中间的对应位置。-LBP algorithm with opencv. Through a 3* 3 matrix template image slide, with the template field of eight around the center pixel and the pixel value comparison, greater than 1, is smaller than 0, arranged clockwise from upper left, then converted to decimal in the corresponding position in the middle of the template.
