Computational Morphology is the analysis of form by computational means. The present paper is more specifically about the construction and manipulation of closed object boundaries through a set of scattered points in 2D. Results are developed in four successive stages of computational morphology: 1. impose a geometrical graph structure on the set of scattered points; 2. construct a polygonal boundary curve from this geometrical graph structure; 3. build a hierarchy of polygonal approximations together with localization informatiion; 4. construct a geometric continuous object boundary. The economic adavantage of this approach is that there is no dependency on any specific data source. It can be used for various types of data sources or when the source is unknown.
