    img =cv2.imread('test5.jpg')
    print(img.shape)
    cv2.imshow('src',img)
    cv2.waitKey(0)
    cv2.destroyAllWindows()
    new_img = LBP(img)
    cv2.imshow('dst',new_img)
    cv2.waitKey(0)
    cv2.destroyAllWindows()

这代码是LBP算法的，有问题，不知道哪里有问题，有种绝望感，本来想趁假期敲敲那些年该敲而没有敲的代码，结果学出了绝望感。记得当年毕业时候找工作，老师当年鼓励我说，你不要自卑，你看能进一个学校的同一个专业的，说明嘛，脑子都差不多的，他们能找到名企，你也可以的，虽然我也进过传说中的名企，但是这么多年我有点承认自己有点笨。岁月静好的时候学习敲代码，都不会呢。啊啊啊啊、。。。。。。吃点东西再学吧。。。
