We study the boundary measures of compact subsets of the d-dimensional Euclidean space, which are closely related to Federer’s curvature measures. We show that they can be comput...
This paper is devoted to the identification of the unknown smooth coefficient c entering the hyperbolic equation c(x)2 t u-u = 0 in a bounded smooth domain in Rd from partial (on ...

Segmentation in volumetric images deals with separating `objects' from their `background' in a given 3D data. Usually, one starts with `edge detectors' that give bi...
Abstract— In this paper, we propose a three-dimensional (3D) measurement method of objects in aquatic environments whose refractive indices or boundary shape of the refraction ar...
Convexity is an important geometric property of many natural and man-made structures. Prior research has shown that it is imperative to many perceptual-organization and imageunder...
