Ondelettes et applications en imagerie et en calcul de surfaces
This thesis is a theorical and numerical contribution to wavelet transform in image processing and surface computing. Group theory approach, multiresolution approach and lters banc approach of wavelets basis are reviewed. The wavelet transform applications concern image compression, discrete curve representation and surface approximation by radial functions. We begin by reviewing di erent image...
متن کاملFamilles de vecteurs
Preuve Soit (E,+, •) un K-espace vectoriel. Soit I un ensemble fini. Une famille (ui)i∈I ∈ E d’éléments de E. — (⇒) Si (ui)i∈I est libre. I est un sous-ensemble fini de I. Puis par la définition 1.1, pour tout toute famille de scalaires (λi)i∈I , on a : ∑ i∈I λi •ui = 0E ⇔ ∀i ∈ I, λj = 0. — (⇐) On suppose que pour tout toute famille de scalaires (λi)i∈I , on a : ∑ i∈I λi • ui = 0E ⇔ ∀i ∈ I, λj ...
متن کاملConstruction De Familles Minimales De Courbes Gauches
Let A be a noetherian local ring, and let C in PA be a family of curves, flat over A. We showed in an earlier paper how to associate to C a locally free sheaf N on PA, and we showed that two families of curves C,C′ are in the same biliaison class if and only if the corresponding sheaves N,N ′ are pseudoisomorphic (generalization of the theorem Rao). In this paper we show how to find all the fla...
