subject1: Yan
subject2: Yifan (some with white shirt, some with black shirts)
subject3: Ann

Note that the naming of videos from Yifan's local directory is 
different from here. In Yifan's local dir, test videos inlcude
those from subject 1,2 and 3. Subject1 is Yifan with
white shirt, subject2 is Ann, subject3 is Yifan with black shirt.
Training videos (all right videos) include some videos from Yan
and some videos from Yifan. 

We also map our naming with the naming in our raw videos backup.
