Title: "A virtual tour of free viewpoint rendering"

Speaker: CÚdric Verleysen (ICTEAM/ELEN, UCL)

Location: "Shannon" Seminar Room (a105)

Place du Levant 3, Maxwell Building, 1st floor

Date / Time (duration): Tuesday 18/12/2012, 15h00 (~ 45')

Abstract:

A principal limitation of the conventional video technology is that the viewpoint is fixed by the camera that captures a scene. Since the last decade, researchers have tried to overcome this limitation by allowing a remote viewer to interactively navigate across the scene. The potential applications of such free viewpoint rendering are tremendous, ranging from 3D TV to scene analysis, and from interactive media, augmented reality to video content/game production, etc.

The purpose of this talk is to give an overview of the recent developments in the field of free viewpoint rendering. Specifically, after the introduction of the concept of virtual camera and its associated acquisition setup, some basic notions of stereo vision will be detailed. By investigating deeper into epipolar geometry and stereo matching, we will argue why the perpetual (troll) war between model-based rendering and image-based rendering is non-sense. The talk will conclude with some thoughts about the synthesis of a virtual view in a sparse camera network.
