A sufficient condition for computing n-finger force-closure grasps of 3D objects

Sahar El Khoury

We address the problem of computing n-finger force-closure grasps of 3D objects. As 3D force-closure grasps involve 6D wrench space, we use Pl¨ucker coordinates and Grassmann algebra, to demonstrate that wrenches associated to any three non-aligned contact ...

Closed-Form Solution to Non-rigid 3D Surface Registration

Pascal Fua, Mathieu Salzmann, Vincent Lepetit

We present a closed-form solution to the problem of recovering the 3D shape of a non-rigid inelastic surface from 3D-to-2D correspondences. This lets us detect and reconstruct such a, surface by matching individual images against a reference configuration, ...

Omnidirectional views selection for scene representation

Pascal Frossard, Ivana Tosic

This paper proposes a new method for the selection of sets of omnidirectional views, which contribute together to the efficient representation of a 3d scene. When the 3d surface is modelled as a function on a unit sphere, the view selection problem is most ...

Progressive coding of 3D objects based on overcomplete decompositions

Pascal Frossard, Pierre Vandergheynst, Ivana Tosic

This paper presents a progressive coding scheme for 3D objects, based on an overcomplete decomposition of the 3D model on a sphere. Due to increased freedom in the bases construction, redundant expansions have shown interesting approximation properties in ...

Progressive low bit rate coding of simple 3D objects with Matching Pursuit

Pascal Frossard, Pierre Vandergheynst, Ivana Tosic

This paper presents a low rate progressive 3D mesh compression scheme for simple genus-zero 3D objects. The proposed scheme is based on signal representation using redundant expansions. 3D model representation is constructed using a Matching Pursuit algori ...

Watermarked 3D Object Quality Assessment

Touradj Ebrahimi, Elisa Drelie Gelasca

This work concerns the developing of new perceptual metrics for 3D watermarking quality assessment. Any water- marking algorithm, to be effective, requires that the distortions is inevitably introduces into the watermarked media is imperceptible. This requ ...

Microfabrication of ceramic components by microstereolithography

Philippe Renaud, Arnaud Bertsch, Sébastien Jiguet

Microstereolithography is a technique that allows the manufacture of small and complex three-dimensional (3D) components in plastic material. Many of the components produced by this technique are too small and too complex to be replicated by molding and, c ...

Compression of 3D models with NURBS

Diego Santa Cruz Ducci

With recent progress in computing, algorithmics and telecommunications, 3D models are increasingly used in various multimedia applications. Examples include visualization, gaming, entertainment and virtual reality. In the multimedia domain 3D models have b ...

Microstereolithography: a review

Philippe Renaud, Arnaud Bertsch, Sébastien Jiguet

Microstereolithography is a technology at the interface of the microengineering and rapid prototyping domains. It has evolved from the stereolithography technique, and is also based on a light-induced layer- stacking manufacturing, As the resolution of the ...

Crack Pattern Simulation Based on 3D Surface Cellular Automaton

Stéphane Gobron

This article describes a method for modeling the propagation of cracks on any 3D surface. This method allows almost any type of cracks on any type of triangulated 3D object. Our model’s main advantage is that it proposes a semi-physical solution, making it ...
