Skeletons and watershed lines in digital spaces
Fernand Meyer · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1990
The analysis of some topological properties of the skeleton in the continuous plane leads us to propose a definition of the digital skeleton. The framework which is developed permits to define and to construct other related remarkable subsets of sets or functions : minimal skeletons conditional bisectors perceptual graphs watershed lines.
