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.

Thanks I knew the examples obviously ! Ill try with these objects though. Making the distinction between on-place-motion and across-frame motion thus ... in a simple way. JM

Check the Gem examples, in Pd-extended go to:
Help menu -> Browser -> Gem -> examples 04.video
See:

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
