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");

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();

}
