马赛克效果

实现图片马赛克代码：

import cv2
import numpy as np
img = cv2.imread('image1.jpg',1)
imgInfo = img.shape
heigth = imgInfo[0]
width = imgInfo[1]
for m in range(100,300):
    for n in range(100,200):
        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)
