[Lrde Annonce] New journal publication

I am happy to announce that the following paper has been accepted for publication in the Journal of Mathematical Imaging and Vision (JMIV): A Tutorial on Well-Composedness Nicolas Boutry (1), Thierry Géraud (1) and Laurent Najman (2) (1) LRDE, EPITA, Le Kremlin-Bicêtre, France (2) Université Paris-Est, LIGM, Équipe A3SI, ESIEE, Marne-la-Vallée, France Abstract: Due to digitization, usual discrete signals generally present topological paradoxes, such as the connectivity paradoxes of Rosenfeld. To get rid of those paradoxes, and to restore some topological properties to the objects contained in the image, like manifoldness, Latecki proposed a new class of images, called well-composed images, with no topological issues. Furthermore, well-composed images have some other interesting properties: for example, the Euler number is locally computable, boundaries of objects separate background from foreground, the tree of shapes is well defined, and so on. Last, but not the least, some recent works in mathematical morphology have shown that very nice practical results can be obtained thanks to well-composed images. Believing in its prime importance in digital topology, we then propose this state-of-the-art of well-composedness, summarizing its different flavours, the different methods existing to produce well-composed signals, and the various topics that are related to well-composedness.
