This paper introduces two kinds of free viewpoint observation systems for sporting events captured with uncalibrated multiple cameras in a stadium. In the first system (Viewpoint...
Most state-of-the-art approaches to action recognition rely on global representations either by concatenating local information in a long descriptor vector or by computing a single...
Although human action recognition has been the subject of much research in the past, the issue of viewpoint invariance has received scarce attention. In this paper, we present an ...
This paper presents a new approachto recognizingmultiagent events observed by a static camera. To track objects robustly, knowledgeabout the groundplaneand the events is used. An ...
A growing body of research is investigating the use of tabletop displays, in particular to support collaborative work. People often interact directly with these displays, typicall...
