We are happy to announce that the following paper has been accepted for publication at the 9th International Symposium on Mathematical Morphology (ISMM) that will take place at Groningen, The Netherlands, on August 24 - 27, 2009: Roland Levillain (1,2), Thierry Géraud (1,2) and Laurent Najman (2) Milena: Write Generic Morphological Algorithms Once, Run on Many Kinds of Images http://publis.lrde.epita.fr/200908-ISMM (1) EPITA Research and Development Laboratory (LRDE) (2) Université Paris-Est, Laboratoire d'Informatique Gaspard-Monge, Equipe A3SI, ESIEE Paris We present a programming framework for discrete mathematical morphology centered on the concept of genericity. We show that formal definitions of morphological algorithms can be translated into actual code, usable on virtually any kind of compatible images, provided a general definition of the concept of image is given. This work is implemented in Milena, a generic, efficient, and user-friendly image processing library.
