#include<iostream>
#include<core\core.hpp>
#include<opencv2\opencv.hpp>
using namespace std;
using namespace cv;
 
int main(int argc,char** argv){
Mat src; 
Mat dst;
src = imread("1.jpg");
if (src.empty())
{
cout << "could not load image.." << endl;
return -1;
}
//namedWindow("input image", CV_WINDOW_AUTOSIZE);
imshow("input_image", src);
medianBlur(src, dst, 3);
//namedWindow("中值的效果", CV_WINDOW_AUTOSIZE);
imshow("中值效果", dst);
waitKey(0);
return 0;
