毛玻璃

原理：将所有像素点随机赋值比其大某个不大的值，如：0-8间的某个值

import cv2import numpy as npimport randomimg = cv2.imread('D:/pythonob/imageinpaint/img/zidan.jpg',1)imgInfo = img.shapeheight = imgInfo[0]width = imgInfo[1]dst = np.zeros((height,width,3),np.uint8)for i in range(0,height-8):    for j in range(0,width-8):        index = int(random.random()*8)#随机数0-8        (b,g,r) = img[i+index,j+index]        dst[i,j] = (b,g,r)cv2.imshow('maoboli',dst)cv2.waitKey(0)效果图：
