another tracking problem
we are trying to build an instalation where a shodow is projected onto a semi transparent screen, behind wich lies a grid of amplifiers, and behind the, the camera that grabs the video for tracking.
basically the user would notice that his or hers shadow would control the volume/pan of the amplifiers behind the screen.
Having explored the excellent jit.cv, i decide not to use shape analyses since i need specific coordinates of the users shadow extremities (seven in all, head, shoulders hands and knees)
two questions i was hoping you could help follow:
1) is there a way to effect a "foreground subtraction"? because the grid of amplifiers is between the screen with thetrackable shadow, and the camera
2) in order tfor he tracking points to stick where we need them to be, is there any alternative to binarized the image? i ask because currently we get a lot of noise with binarized images...
using a mac, btw
thanks for the time and patiente
