nous avons développé une nouvelle variété d'éléments structurants pour la morphologie mathématique Ces éléments s'appuient sur une vision intuitive de l'idée de voisinage dans un espace dont une des dimensions est le temps et, d'une part, apportent une amélioration signicative aux résultats visuels de ltrage, d'autre part ,
approximation à N termes pour les ondelettes sans rebonds montrent que l'étape de mise-à-jour non-linéaire n'est pas aussi productive pour ces ondelettes que peut l'être l'étape de mise-à-jour linéaire. Il y a donc un travail à eectuer sur les opérateurs de mise-à-jour non-linéaires an qu'ils se combinent harmonieusement et productivement avec l'étape de prédiction qui a fait ses preuves ,
