help!: extracting X-Y data for multiple blobs

    May 09 2006 | 9:21 pm
    I'm desperately looking for some advise concerning webcam processing.
    At the moment i'm using jit.findbounds and a framedifference-patch to extract the movement of a person in a space. (the webcam is mounted on the ceiling).
    This works quite alright, untill more people show up.
    I would be very grateful if someone could supply me some tips for X-Y tracking-data for multiple blobs simultaniously (say 3 max).
    Thanks in advance!
