Soooo.... I am using the Haar face detection to find the faces when I lose them and update them every 75 frames. I am using Zhang's Real-time Compressive Tracker for the tracking. It does not perform as well on tango dancers. Well, nothing does! I am using pretty crude depth segmentation, skin color tracking (also the crude version) & only looking at the upper fourth of any blob to track something or detect a face. Only looking at the upper fourth of any blob means it will not catch lifts and dips (unless I can separate the couple), but those are really rare in tango social dance.
So, it does NOT have continuity between the faces at the moment. Or at least, every 75 frames it loses continuity. So the next step will be creating the continuity. So, that means when I lose a face, I need to find it again via face detect & check whether THAT image is similar. I think I may dig in the code for the tracker I'm using since it is obviously doing SOMETHING like that. Also, since the tracker updates & learns, that means it should drift less (I'm guessing). That means that eventually I can trust it not to drift less...
I could also make my face detection faster....
Also, To be honest I'm a little horrified at some of my mistakes (dancing) in this video, especially after repeated viewing. I was tired! Nevertheless!
