After we compute
,
we
replace the potential force
in the dynamic
snake equation of (7) by
,
yielding

(13) 
We call the parametric curve solving the above dynamic equation as
a GVF snake. This equation is solved in similar fashion to the
traditional snake  i.e., by discretization and iterative solution.
