Visual information, in the form of images and video, comes from the interaction of light with objects. Illumination is a fundamental element of visual information. Detecting and interpreting illumination effects is part of our everyday life visual experien ...
Computer vision applications are able to model and reconstruct three dimensional scenes from several pictures. In this work, we are interested in the group of algorithm that register each image with respect to the model and aim at constructing a model of t ...
Nowadays, it becomes possible to show a live virtual stage application allowing a human's real time participation by motion capture. The big problem in participatory animation is figuring out where to place the camera and in what direction to point it to p ...
We present a fully automated approach to camera registration for augmented reality systems. It relies on purely passive vision techniques to solve the initialization and real-time tracking problems, given a rough CAD model of parts of the real scene. It do ...
It is argued that global illumination should be modeled separately from other incidents that change the appearance of objects. The effects of intensity variations of the global illumination are discussed and constraints deduced that restrict the shape of a ...
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 ...
Rendering and animating in real-time a multitude of articulated characters presents a real challenge, and few hardware systems are up to the task. Up to now, little research has been conducted to tackle the issue of real-time rendering of numerous virtual ...

We present an augmented reality system that relies on purely passive techniques to solve the real-time registration problem. It can run on a portable PC and does not require engineering of the environment, for example by adding markers. To achieve this res ...
