Real-time virtual view rendering for video communication systems using OpenCL

Multi-view video (MVV) offers many possibilities for video communication systems. The creation of virtual views allows to change the viewer´s perspective interactively on the receiver side. In this paper we propose a real time algorithm capable of rendering virtual views with a high image quality without the support of scene geometry information. We utilize the highly parallel architecture of recent GPUs for online depth estimation and a sophisticated but generally available shader architecture for efficient rendering. Using these methods we are able to render virtual views with resolutions of up to 3600×3000 with a frame rate of more than 25 frames per second.
