Opencv_2_ 图像色彩空间转换

ColorInvert.h 内容如下：

#pragma once
#include <opencv.hpp>
using namespace std;
#include <opencv.hpp>
using namespace cv;
using namespace std;
class ColorInvert{
public :
    void colorSpaceInvert(Mat&image);
};

ColorInvert.cpp 内容如下：

#include "ColorInvert.h"

void ColorInvert::colorSpaceInvert(Mat& image)
{
    Mat gray, hsv;
    cvtColor(image, hsv, COLOR_BGR2HSV);
    cvtColor(image, gray, COLOR_BGR2GRAY);
    imshow("HSV", hsv);
    imshow("灰度", gray);
    imwrite("E:/2024/Test/opencv/hsv.png", hsv);
    imwrite("E:/2024/Test/opencv/gray.png", gray);
}

main.cpp内容如下：

#include <iostream>
#include <opencv.hpp>
#include "ColorInvert.h"
using namespace std;
using namespace cv;

int main()
{
    Mat src = imread("E:/2024/Test/opencv/test1.png");
    if (src.empty()) {
        cout << "load pic fail" << endl;
        return -1;
    }
    namedWindow("输入窗口", WINDOW_FREERATIO);
    imshow("输入窗口", src);
    ColorInvert coInvert;
    coInvert.colorSpaceInvert(src);
    waitKey(0);
    destroyAllWindows();
}
