     The application starts up extracting the ORB features and descriptors from the input image and
     then uses the mesh along with the [Möller–Trumbore intersection

     to compute the 3D coordinates of the found features. Finally, the 3D points and the descriptors
     are stored in different lists in a file with YAML format which each row is a different point. The
     technical background on how to store the files can be found in the @ref tutorial_file_input_output_with_xml_yml
