生活就像大海，我就像一条咸鱼，在浩瀚的海洋中边浪边学，这是opencv笔记系列中的「图像修补」。bash

世间万图，皆可修补。小编边浪边学，顺带以很咸鱼的方式把它们记录下来。ui

首先，对原图像进行一些小小的“损坏”spa

import cv2
import numpy as np
img = cv2.imread('test1.jpg',1)
for i in range(200,300):
    img[i,200] = (255,255,255)
    img[i,200+1] = (255,255,255)
    img[i,200-1] = (255,255,255)
for i in range(150,250):
    img[250,i] = (255,255,255)
    img[250+1,i] = (255,255,255)
    img[250-1,i] = (255,255,255)
cv2.imwrite('damge.jpg',img)
cv2.imshow('image',img)
cv2.waitKey(0)
复制代码

破坏后的图像显示以下，可见人物左边的天空，有一小块被“破坏”了code

接下来读取这张图片，进行修补cdn

img = cv2.imread('damge.jpg',1)
height = img.shape[0]
width = img.shape[1]
paint = np.zeros((height,width,1),np.uint8)
cv2.imshow('img',img)
for i in range(200,300):
    paint[i,200] = 255
    paint[i,200+1] = 255
    paint[i,200-1] = 255
for i in range(150,250):
    paint[250,i] = 255
    paint[250+1,i] = 255
    paint[250-1,i] = 255
imgDst = cv2.inpaint(img,paint,3,cv2.INPAINT_TELEA)
cv2.imshow('dst',imgDst)
cv2.waitKey(0)
复制代码

修补后图像显示以下，已经和原图像没啥两样了blog
