The workshop SIGMA’2016 is organized by SMAI-SIGMA, one of the activity groups of the SMAI (Société de Mathématiques Appliquées et Industrielles). It aims at gathering specialists of the following main domains: Signal-Image, Geometric Modelling, Computational Geometry, Approximation. The workshop will be composed of invited plenary talks given by international experts in these fields, and of contributed (oral or poster) presentations.
