A novel framework for 3D reconstruction and analysis of ancient inscriptions
Studying ancient inscriptions is based up to date mostly on observation and manual analysis by means of which epigraphists attempt to establish a geographical and chronological cla...

Arrangements on Parametric Surfaces II: Concretizations and Applications
We describe the algorithms and implementation details involved in the concretizations of a generic framework that enables exact construction, maintenance, and manipulation of arran...

Rational two-parameter families of spheres and rational offset surfaces
The present paper investigates two-parameter families of spheres in R3 and their corresponding two-dimensional surfaces in R4 . Considering a rational surface in R4 , the envelo...

A Convergent Finite Volume Scheme for Diffusion on Evolving Surfaces
Abstract. A finite volume scheme for transport and diffusion problems on evolving hypersurfaces is discussed. The underlying motion is assumed to be described by a fixed, not ne...

Parameterization-Invariant Shape Comparisons of Anatomical Surfaces
—We consider 3D brain structures as continuous parameterized surfaces and present a metric for their comparisons that is invariant to the way they are parameterized. Past compari...

Irreducible triangulations of surfaces with boundary
A triangulation of a surface is irreducible if no edge can be contracted to produce a triangulation of the same surface. In this paper, we investigate irreducible triangulations o...

Studying brain morphometry using conformal equivalence class
Two surfaces are conformally equivalent if there exists a bijective angle-preserving map between them. The Teichm

Shape Defined Panoramas
Panoramic projections are often defined by the geometric surfaces used to derive the projections' equations (e.g., spherical and cylindrical panoramas). The parameterization o...

Crease Surfaces: From Theory to Extraction and Application to Diffusion Tensor MRI
—Crease surfaces are two-dimensional manifolds along which a scalar field assumes a local maximum (ridge) or a local minimum (valley) in a constrained space. Unlike isosurfaces, ...
