如何在OpenCV中设置KMEANS_USE_INITIAL_LABELS的坐标？

cv::kmeans(InputArray data, int K, InputOutputArray bestLabels, TermCriteria criteria, int attempts, int flags, OutputArray centers = noArray())

#include <opencv2/opencv.hpp>

int main() {
    // 准备输入数据
    cv::Mat data = (cv::Mat_<float>(6, 2) << 1, 1, 2, 1, 4, 3, 5, 4, 7, 5, 8, 6);

    // 初始化聚类中心
    cv::Mat centers = (cv::Mat_<float>(2, 2) << 1, 1, 7, 5);

    // 设置附加标志
    int flags = cv::KMEANS_USE_INITIAL_LABELS;

    // 调用cv::kmeans函数
    cv::Mat bestLabels, bestCenters;
    cv::kmeans(data, 2, bestLabels, cv::TermCriteria(), 10, flags, bestCenters);

    // 输出结果
    std::cout << "Best Labels: " << bestLabels << std::endl;
    std::cout << "Best Centers: " << bestCenters << std::endl;

    return 0;
}
