Hi Chris,
gem has a pix_blub object, you might use that in conjunction with pix_background to identify moving objects and their motion vectors. not sure how far this will get you, though ... I'm afraid pd /gem isn't as advanced as EyesWeb in this respect.
On the other hand, isn't EyesWeb open sourced, apart from the intel image processing libs? Maybe porting some stuff won't be too hard.
hope this helps, thoralf.
