5、opencv的Mat介绍

Mat类创建

#include <opencv2/opencv.hpp>using namespace cv;void main(){    Mat img1=imread("E://1.jpg");    Mat img2(img1);    Mat img3=img1;    Mat img4=img1.clone();    Mat img5;    img1.copyTo(img5);    cvtColor(img1,img1,CV_BGR2HSV);    imshow("img1",img1);    imshow("img2",img2);    imshow("img3",img3);    imshow("img4",img4);    imshow("img5",img5);    waitKey(0);}
