图像色彩空间转换

#include<iostream>
#include<opencv2/opencv.hpp>

using namespace std;
using namespace cv;

//图像色彩空间转换
void colorSpace(Mat &image)

	Mat gray, hsv;

	//色彩空间转换
	cvtColor(image, hsv, COLOR_BGR2HSV);
	cvtColor(image, gray, COLOR_BGR2GRAY);

	//图片显示
	imshow("HSV", hsv);
	imshow("灰度", gray);

	//图片保存
	imwrite("C:\\\\Users\\\\四明\\\\Pictures\\\\hsv.jpg", hsv);
	imwrite("C:\\\\Users\\\\四明\\\\Pictures\\\\gray.jpg", gray);



int main()

	string path = "C:\\\\Users\\\\四明\\\\Pictures\\\\QQ图片20200608155343.jpg";
	Mat img = imread(path);
	if (img.empty())
	
		cout << "加载图片失败" << endl;
		return -1;
	
	namedWindow("image", WINDOW_FREERATIO);
	imshow("image", img);
	colorSpace(img);
	waitKey(0);
	destroyAllWindows();
	return 0;
