Robust Feature Point Extraction and Tracking for Augmented Reality

Touradj Ebrahimi

For augmented reality applications, accurate estimation of the camera pose is required. An existing video-based markerless tracking system, developed at the ITS, presents several weaknesses towards this goal. In order to improve the video tracker, several ...

Hybrid Tracking for Augmented Reality

Touradj Ebrahimi

Accurate registration between real and virtual objects is critical for Augmented Reality (AR) applications. State of the art shows that no tracking device is individually adequate. We present a data fusion framework that combines orientation measurements o ...

Tracking and User Interface for Mixed Reality

Touradj Ebrahimi, Yousri Abdeljaoued

This chapter introduces the field of Mixed Reality that merges the real and virtual worlds seamlessly. To develop a Mixed Reality system, two fundamental problems should be addressed: tracking and user interface. Tracking in Mixed Reality is defined as the ...

Functional, mechanical and geometrical adaptation of the arterial wall of a non-axisymmetric artery in vitro

Nikolaos Stergiopoulos, Paolo Silacci, Martin Zulliger

Vascular remodeling is an adaptive response to variations in the hemodynamic environment acting on the arterial wall. Remodeling translates into changes of structure, geometry and mechanical properties of the artery. Our aim was to study the remodeling res ...

Multi modal tracking in complex environments for augmented reality applications

This work presents a model based real-time method for tracking 3D objects with a monocular camera. Our goal is to implement a tracking algorithm with a non conventional robustness in order to be used in hostile environments. We achieve this goal by integra ...

A probabilistic framework for joint head tracking and pose estimation

Jean-Marc Odobez, Silèye Oumar Ba

Head Tracking and pose estimation are usually considered as two sequential and separate problems: pose is estimated on the head patch provided by a tracking module. However, precision in head pose estimation is dependent on tracking accuracy which itself c ...

Real-time augmented face

Daniel Thalmann, Pascal Fua, Vincent Lepetit

This real-time augmented reality demonstration relies on our tracking algorithm described in V. Lepetit et al (2003). This algorithm considers natural feature points, and then does not require engineering of the environment. It merges the information from ...

Flow Investigation in a Francis Draft Tube : the Flindt Project

François Avellan

The flow investigation in a elbow draft tube is presented. After a review of the existing works related to the flow analysis of such component, the need of an experimental validation of the CFD tools is discussed with respect the practical interest of impr ...

Metropolis light transport for participating media

Mark Pauly

We show how Metropolis light transport can be extended both in the underlying theoretical framework and the algorithmic implementation to incorporate volumetric scattering. We present a generalization of the path integral formulation that handles anisotrop ...
