Water-skel
Résumé
This paper introduces a distance-based skeleton approach. It starts from a set of prese- lected shape extremities. The extremities lead to the definition of markers on the object boundary. These markers are then immersed on the inverse distance function. Finaly a watershed provides a thin, homotopic and centered skeleton linking the provided ex- tremities. The main contribution of the paper is the interpretation of the skeleton as a watershed process from markers, a well known operator and for which efficient implemen- tations exist.
