利用opencv4.8和c++求得区域质心并标记代码

以下是利用OpenCV4.8和C++求得区域质心并标记的代码：

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
    Mat src = imread("test.jpg", 1); //读取图像
    Mat gray;
    cvtColor(src, gray, COLOR_BGR2GRAY); //将图像转换为灰度图像

    threshold(gray, gray, 100, 255, THRESH_BINARY); //二值化处理

    vector<vector<Point>> contours;
    vector<Vec4i> hierarchy;
    findContours(gray, contours, hierarchy, RETR_TREE, CHAIN_APPROX_SIMPLE); //寻找轮廓

    for (int i = 0; i < contours.size(); i++)
    {
        Moments mu = moments(contours[i], false); //计算轮廓的矩
        Point2f center(mu.m10 / mu.m00, mu.m01 / mu.m00); //计算轮廓的质心
        circle(src, center, 5, Scalar(0, 0, 255), -1); //在图像上标记质心
    }

    imshow("src", src);
    waitKey(0);
    return 0;
}
