如何将tif图像从cv::Mat数据类型转换为Eigen::MatrixXf

#include <opencv2/opencv.hpp>
#include <Eigen/Dense>

cv::Mat image = cv::imread("image.tif", cv::IMREAD_GRAYSCALE);

Eigen::MatrixXf matrix(image.rows, image.cols);
for (int i = 0; i < image.rows; i++) {
    for (int j = 0; j < image.cols; j++) {
        matrix(i, j) = static_cast<float>(image.at<uchar>(i, j));
    }
}

#include <opencv2/opencv.hpp>
#include <Eigen/Dense>

int main() {
    cv::Mat image = cv::imread("image.tif", cv::IMREAD_GRAYSCALE);

    Eigen::MatrixXf matrix(image.rows, image.cols);
    for (int i = 0; i < image.rows; i++) {
        for (int j = 0; j < image.cols; j++) {
            matrix(i, j) = static_cast<float>(image.at<uchar>(i, j));
        }
    }

    // 进一步处理Eigen::MatrixXf对象...

    return 0;
