opencv 实现打马赛克

1，我们需要屏蔽图片中的一部分图片，所以我们需要用到马赛克，代码实现如下；

import cv2
import numpy as np
img = cv2.imread('image0.jpg',1)
imgInfo = img.shape
height = imgInfo[0]
width = imgInfo[1]
for m in range(100,300):
    for n in range(100,200):
        # pixel ->10*10
        if m%10 == 0 and n%10==0:
            for i in range(0,10):
                for j in range(0,10):
                    (b,g,r) = img[m,n]
                    img[i+m,j+n] = (b,g,r)
cv2.imshow('dst',img)
cv2.waitKey(0)

实现结果：
