Sorry, you said simple, so that's a simple start :) For making the
distinction between people walking and standing in place, a simple
thing would be to bump up the threshold of what counts as movement.
Another would be to do multi-blob detection and look for x,y movement
in a direction, or that exceeds a certain threshold. Check the
'mapping' library (included in Pd-extended) for an array of techniques
of working with the data that will most likely be helpful here.

Check the Gem examples, in Pd-extended go to:

Hi list
Video frame analysis : I would like to be able to make a
difference between
- motions of poeple passing by (displacements)
- motions of poeple standing by somewhere (and slightly moving on
place, presence)
in a simple way ... anyone got an idea of with what pix_objects to start ?
thanks jean-marie
