/** @brief Maps cv::Mat data to an Eigen::TensorMap.
|
||||
|
||||
The method wraps an existing Mat data array with an Eigen TensorMap of shape (H x W x C) where:
|
||||
H = number of rows
|
||||
W = number of columns
|
||||
C = number of channels
|
||||
|
||||
Explicit instantiation of the return type is required.
|
||||
|
||||
@note Caller should be aware of the lifetime of the cv::Mat instance and take appropriate safety measures.
|
||||
The cv::Mat instance will retain ownership of the data and the Eigen::TensorMap will lose access when the cv::Mat data is deallocated.
|
||||
|
||||
The example below initializes a cv::Mat and produces an Eigen::TensorMap:
|
||||
\code
|
||||
float arr[] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11};
|
||||
Mat a_mat(2, 2, CV_32FC3, arr);
|
||||
Eigen::TensorMap<Eigen::Tensor<float, 3, Eigen::RowMajor>> a_tensormap = cv2eigen_tensormap<float>(a_mat);
