[C++] Eigen to OpenCV conversion 변환

Eigen::MatrixXf을 cv::Mat으로 변환해보자

Eigen to CV

#include <opencv2/core/eigen.hpp>

int num_rows = 100;
int num_cols = 100;
Eigen::MatrixXf mat(num_cols, num_rows);

cv::Mat image(num_cols, num_rows, CV_32FC1);
cv::eigen2cv(mat, image);

CV to Eigen

void cv2eigen(const Mat& src, Eigen::Matrix<_Tp, _rows, _cols, _options, _maxRows, _maxCols>& dst)
