iter_gcsf Iterated gcsf




$ \bigcirc$Command Synopsis


iter_gcsf [-g g] [-l l] [-e e] [-a a] [-n n] [-N N] [-v] in out



-g g : power of curvature (default 1)

-l l : last scale (default 1)

-e e : (for gcsf) sampling precision (default 3.)

-a a : (for gcsf) erosion area (default 4.)

-n n : (for gcsf) or minimal # of iterations (default 1)

-N N : number of output curves (default 5)

-v : verbose mode

in : input curve (Dlist)

out : output curves (Dlists)

$ \bigcirc$Description


This module calls the gcsf module to compute the generalized shortening flow of a plane curve. The geometric parameters are sent to gcsf. The number of displayed curves is N, so that the scale difference between two consecutive curves is l /N.
