General software features

Watershed is the fundamental tool of mathematical morphology for image segmentation. The authors of this software have proposed a formal definition of this notion in discrete spaces. In this framework, the watershed becomes a transformation that preserves some topological characteristics of an image. This leads to a series of fundamental properties which had never been established previously.

In order to permit its practical application, we propose quasi-linear algorithms for the topological watershed, which are implemented in this software.
