how to use the HP_groups to generate the 3D point cloud using COLMAP

Dear Sir or Madam,
I would like to use the HP_groups to generate the 3D point cloud by colmap. But I find that using Colmap to import the features and the matches needs the descriptor of the features. I know there is an illumination-invariant descriptor in the paper. When I run the demo, I can't find the descriptor. Is it in the  'vSet.mat'?
