Converting a .mat file from MATLAB into cv::Mat matrix in OpenCV

Question

I have some MATLAB code that I want to migrate to OpenCV. The data that the MATLAB code uses is stored in a .mat file which is then loaded at run time.

I converted

Besides using XML/YAML file storages suggested by @Drodbar, you can also try cvmatio, which provides APIs to directly load MATLAB MAT files to OpenCV.

The code will be simply like:

#include "MatlabIO.hpp"
#include "MatlabIOContainer.hpp"

...

// load the MATLAB MAT file
MatlabIO matio;
bool ok = matio.open("-path-to-mat-file.mat", "r");
if (!ok) return -1;

// read all of the variables in the file
std::vector variables;
variables = matio.read();
matio.close();

// load the matrix by name in OpenCV style
cv::Mat basis = matio.find(variables, "B")
