OpenCV马赛克

#马赛克
import cv2
import numpy as np
import matplotlib.pyplot as pltimg = cv2.imread('coins.jpg',1)
imgInfo = img.shape
height = imgInfo[0]
width = imgInfo[1]for m in range(200,400):  #m,n表示打马赛克区域for n in range(200,400):# pixel ->10*10if 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)#原始图像
img0 = cv2.imread('coins.jpg',1)
img_bgr2rgb1 = cv2.cvtColor(img0, cv2.COLOR_BGR2RGB)
plt.imshow(img_bgr2rgb1)
plt.show()#马赛克图像
img_bgr2rgb0 = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
plt.imshow(img_bgr2rgb0)
plt.show()
