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?!
