2D première génération. Ces transformées ont des atomes qui ressemblent a ̀ des plans ou des filaments, et permettent de bien représenter les éléments de co-dimension un et deux dans un volume 3D. Nous appliquons ces transformées du dbruitage et de l’inpainting de données 3D et 2D+temps (vidéo). Abstract – We present two new sparse 3D transforms, which are the two 3D extensions to the first generation 2D curvelets. These transforms have plane- and filament-like atoms, and aim at representing elements of co-dimension one or two in a 3D volume. We show the applicability of these transforms to 3D data and 2D video inpainting and denoising.
