Question about VID_train_15frames.txt

[KevinQian97]

Hi， I have a question about your VID_train_15frames.txt file. In each line, there are four parameters. for example: train/ILSVRC2015_VID_train_0000/ILSVRC2015_train_00000000 1 10 300 Apparently the first one is the index of video. However, I am wondering what the three left means and how they works. In your codes, you call them frame_id,frame_seg_id,frame_seg_len.
