General software features

We extended the topological concepts of the 2D binary images to the 2D graylevel images, by considering all the cross-sections (thresholds) of the images. This led us to propose new methods for segmenting, filtering, and enhancing grayscale images. These methods are based on operators that either preserve or selectively modify topology [CBB01,BEC97].

Context in which the software is used

Used for the research of the team, and also in several research projects, see http://www.esiee.fr/~info/a2si/projets.html.
