如何在opencv (c++)中计算标记组件(二值图像)之间的成对距离

cv::Mat binaryImage = ...; // 二值图像
cv::Mat labels;
cv::connectedComponents(binaryImage, labels);

cv::Mat stats;
cv::Mat centroids;
cv::connectedComponentsWithStats(binaryImage, labels, stats, centroids);

int numComponents = stats.rows;
for (int i = 1; i < numComponents; i++) {
    for (int j = i + 1; j < numComponents; j++) {
        cv::Point centroid1(centroids.at<double>(i, 0), centroids.at<double>(i, 1));
        cv::Point centroid2(centroids.at<double>(j, 0), centroids.at<double>(j, 1));
        double distance = cv::norm(centroid1 - centroid2);
        // 处理距离值，可以根据需求进行进一步操作
    }
}
