opencv 二值化和灰度

灰度化

int main()

{
Mat edges=imread("1.jpg");

Mat edge, grayImage;
cvtColor( edges, grayImage,CV_BGR2GRAY);
blur(grayImage,edge,Size(3,3));
imshow("读取视频",edge);
waitKey(0);


return 0;

}

二值化

int main()
{
Mat edges=imread("1.jpg");

Mat edge, grayImage;
cvtColor( edges, grayImage,CV_BGR2GRAY);
threshold(grayImage, edge, 100, 255, 0);
blur(grayImage,edge,Size(3,3));
imshow("读取视频",edge);
waitKey(0);


return 0;
}
