motion detection – tracking multiple objects

hi,

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?!

thanks
hendrik
