Viewpoint quality and scene understanding

Abstract

Virtual worlds exploration techniques become nowadays more and more important. The methods are used in wide variety of domains — from graph drawing to robot motion. This paper is dedicated to virtual world exploration techniques which have to help a human being to understand a 3d scene. Improved methods of viewpoint quality estimation are presented in the paper. Using these methods, a real-time technique allowing to choose a “good” viewpoint for a virtual scene is also proposed.
