OpenCV对图像进行缩放显示

#include "opencv2/opencv.hpp"#include <iostream>using namespace std;using namespace cv;int main(){cv::Mat imagesrc = cv::imread("test.png");//读取图像if (!imagesrc.data){cout<<"no image can be load!"<<endl;return 0;}double fScale = 0.1;//缩放系数//计算目标图像的大小Size dsize = Size(imagesrc.cols*fScale, imagesrc.rows*fScale);Mat imagedst = Mat(dsize, CV_32S);resize(imagesrc, imagedst, dsize);cv::namedWindow("openCV");//创建窗口cv::imshow("openCV", imagedst);//显示图像cv::waitKey();//cv::imwrite("lena.bmp", imagesrc);//保存图像return 1;}
