In this paper we generalize the concept of digital topology to arbitrary dimension n, in the context of (2n, 3n−1)-adjacency. We define an n-digital image P as an uplet ( Z n, R , H), where H is a finite subset of Z n and R represents the adjacency

We introduce the notion of digital n-pseudomanifold and digital n-weakmanifold in (n+1)-digital image, in the context of (2n, 3n-1)- adjacency, and prove the digital version of the Jordan-Brouwer separation theorem for those classes. To accomplish th

We present a new algorithm for ray tracing rational parametric surfaces based on implicitization and inversion. Each patch is associated with a pre-computed square matrix which represents an implicit version of the given parametric surface. This matr

La representation integrale de l'erreur d'interpolation dans le cas a une ou plusieurs variables est presentee comme une generalisation de la methode du Wronskien dans le cas a une variable. Ceci est base sur la construction d'un systeme d'operateurs

In this paper we introduce the new notion of n-pseudomanifold and n-weakmanifold in an (n+1)-digital image using (2(n+1),3(n+1)−1)-adjacency. For these classes, we prove the digital version of the Jordan–Brouwer separation theorem. To accomplish

We consider a generalization of Wronskian methodsfor the case of one and several variables. The integral representation is based on the construction of a system of differential operators associated with the basis interpolant functions and en the Neum

In this paper, we present a method based on a quadratic spline quasi-interpolant for the estimation of integral properties of a planar closed curve. The latter include the length, area, center of gravity and moment of inertia of the given curve. Then
