When Convex Analysis Meets Mathematical Morphology on Graphs
International audience In recent years, variational methods, i.e., the formulation of problems under optimization forms, have had a great deal of success in image processing. This may be accounted for by their good performance and versatility. Conversely, mathematical morphology (MM) is a widely rec...
