I know this is an odd question..But...I'm involved in a project in which the idea is to create the reverse of a green screen effect by having chroma-key applied to the person rather than the background....My question is how possible is it to key out certain elements of a person?..The idea also involves motion tracking another object onto them simultaneously....something which I would imagine is impossible. The keying of items of clothing would happen to voluntary members of the public in a public space. These keyed areas would then be replaced with items which would ideally track to the person. I've come across plugins for AE which do live keying but I haven't been able to find a similar live motion tracking plugin. I'm assuming this doesn't exist due to After Effects being post production software..not software to edit content in real time. Any thoughts or suggestions would be awesome. Or even just confirmation that this isn't possible.
This would be possible with some custom software, though. You might consider a framework like Quartz Composer or Processing/OpenCV which can do facial detection/tracking.
