Arguments:

Description:

Retrieve list of edgels (and their normals) that go around a 2D binary silhouette.

When specified, arguments x0,y0 are the 2D coordinates of the starting point (must be located at the edge of the binary silhouette).
Output image has 3 channels [x,y,n] where x and y are the 2D coordinates of the edgel point, and n is the orientation of its associated canonical normal (can be { 0=[1,0] | 1=[0,1] | 2=[-1,0] | 3=[0,-1] }.
