About visual_features.tar.gz

[ffcarina]

Hello! I noticed that there is a "visual_features.tar.gz" file in the features file url you provided. I have downloaded it and decompressed it, and the file structure is as follows:

• matlab_resnet_faces
  • train
    • frame_1_1.mat
    • frame_1_2.mat
    • frame_x_x.mat
      ...
  • dev
  • test

Because there is no README file, so I cannot know the meaning or source of these files. Can you explain it to me? Hope to hear from you. Thank you!
