motion detection - tracking multiple objects

    Apr 06 2006 | 1:39 pm
    i am trying to build an engine (automated - for a video installation)
    that tracks and follows multiple persons (camera in topview). I am
    using the cv.jit bundle by Jean-Marc Pelletier, which is a great
    help, but i am getting stuck somewhere in logics. I manage to isolate
    the moving persons from the background and have them as white blobs
    in a single plane matrix (either through background subtraction or
    optical flow).
    Through labeling (cv.jit.label) the different blobs i should manage
    to identify the different blobs (either from top-left to bottom-right
    or in size depending on the mode) but here it goes not as i hoped ..
    the blobs (moving persons) are changing place or each blob changes in
    size, so they constantly change place in order.
    Anybody an idea on how to solve this?!
