    Compactly supported radial basis functions
    (Université de Bordj Bou Arreridj Faculty of Mathematics and Computer Science, 2023) TAKOUK, Dalila
    This thesis deals with the applications of compactly supported radial basis functions for high dimensional reconstruction of surfaces (images) based on irregular samples. These methods without mesh (meshfree) based on the introduction of radial basis functions, contrary to traditional methods, namely finite element (FEM) and finite difference (FDM) methods. We try to introduce the concept of this technique through several applications Cette thèse traite les applications des fonctions de base radiale, à support compact (CSRBF), pour la reconstruction bidimensionnelle de surfaces (images) à partir d’échantillons irréguliers. Ces méthodes sans maillage (meshefree) qui reposent sur l’introduction des fonctions de base radiale, contrairement, aux méthodes traditionnelles, a savoir la méthode des éléments finis (FEM) et la méthode des différences finies (FD).
