Video camera tracking?

I've posted a link to the footage of the woman who fell onto the tracks in a New York subway station (for those of you that haven't seen it, don't worry, she was fine).

If you look at the film there are boxes forming around people's bodies, arms etc - presumably to do some sort of tracking with moving cameras? Is this common? I didn't realise they could do this. How does this work? And if it is for automatic tracking, how do they decide who to follow in a busy station? Does it really work?

20 years on from the Berlin wall coming down it seems Big Brother is much smarter than he used to be.

Re: Video camera tracking?

If I have my digital camera set to auto-focus, it will form boxes around what it thinks may be the intended subject of the photo, I've not read the paperwork but I assume that it is to help me see what it will focus on if I take the picture right then.

I imagine the video you mention functions in a similar way - picking out likely prospects for focus as it goes.

yeah, there's quite a lot of investment in face recognition/detection technology. it seems to be very much in demand at the moment.
