%X Active contours are useful tools for segmenting
images. The classical formulation is given in the spatial domain
and is based on a second order system. The formulation based
on a frequency-domain analysis leads to a simple formulation
and design, offering an important computational saving in
comparison to the original one. The frequency-based formulation
also offers a new perspective for studying the convergence of
the snake. This paper addresses an analysis and optimization
for a snake-based segmentation algorithm. The study allows us
to choose optimum values of the system dynamic parameters
in the design of the active contour for improving its speed of
convergence in a segmentation problem.
