如圖為掩模圖像，接下來使用inpaint就可以對(duì)圖像進(jìn)行修復(fù)了。

二、源碼

#include <iostream>
#include<opencv2/opencv.hpp>
#include<opencv2/photo.hpp>
using namespace cv;
using namespace std;

/*
void inpaint(
		InputArray src,   原圖
		InputArray inpaintMask, 二進(jìn)制掩模，指示要修復(fù)的像素
		OutputArray dst,  目標(biāo)圖像
		double inpaintRadius, 像素周圍的鄰域補(bǔ)繪。通常，如果要修復(fù)的區(qū)域很小，則使用較小的值僅產(chǎn)生較少模糊
		int flags     INPAINT_NS  或 INPAINT_TELEA
		)
