Hello!

	Are there any Toolboxes out there for doing motion analysis?  What I 
want to do is calculate velocity of shedding ice particles.  I have a sequence 
of frames and if I can find the distance, in pixels, from a reference point in 
the frame to the ice particle I can calculate the velocity.  The problem is that
from frame to frame the reference point may not have the same x,y coordinate. 
Selecting the reference point manually may not be quite accurate.  The same 
problem holds for selecting the point on the ice shape.  

	Perhaps it is possible to do this with the routines packaged in Khoros?

Thanks for any light you can shed on this (no pun intended!!)
