[Insight-users] Urgent Help: Equation of the Geodesic Active Contour

[OnezerO]

I need to present a example of the geodesic active contour tomorrow, i've
already make the code and the program itself, and it work fine. but i'm kind
of weak in the theorical part of this filter, can anyone help me with this?
i read the Caselles paper but i dind't get so much, where can i find a
simply explanation of the road of pass from general active contour to
geodesic active contour? and the equations that are involved in this? 
 
please!
Regards
Oz.
