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.
