A robust evolutionary algorithm for the recovery of rational Gielis curves

2013

International audience; Gielis curves (GC) can represent a wide range of shapes and patterns ranging from star shapes to symmetric and asymmetric polygons, and even self intersecting curves. Such patterns appear in natural objects or phenomena, such as flowers, crystals, pollen structures, animals, or even wave propagation. Gielis curves and surfaces are an extension of Lamé curves and surfaces (superquadrics) which have benefited in the last two decades of extensive researches to retrieve their parameters from various data types, such as range images, 2D and 3D point clouds, etc. Unfortunately, the most efficient techniques for superquadrics recovery, based on deterministic methods, cannot…

Traitement linéaire du signal numérique

1998

International audience; Le signal numérique et son traitement sont devenus des thématiques majeures des Sciences pour l'Ingénieur depuis que les progrès de l'électronique numérique programmée ont rejeté de plus en plus loin les contraintes de bande passante et de période d'échantillonnage.Cet ouvrage propose de considérer le signal numérique et son traitement comme un ensemble cohérent indépendant de l'analyse du signal continu. Ce point de vue a l'avantage pédagogique de la simplicité de l'approche. Les mathématiques nécessaires restent élémentaires et la présentation des principaux concepts et techniques de traitement ne requiert qu'un niveau Bac scientifique ou technologique. De nombreux…
