Abstract

In recent years, some Video-Based Rendering methods have advanced from off-line rendering to on-line rendering. However very few of them can handle moving cameras while recording. Moving cameras enable to follow an actor in a scene, come closer to get more details or just adjust the framing of the cameras. In this paper, we propose a new Video-Based Rendering method that creates new views of the scene in live from four moving webcams. These cameras are calibrated in real-time using multiple markers. Our method fully uses both CPU and GPU and hence requires only one consumer grade computer.
