Interactive Free Viewpoint Video From Multiple Stereo

We present a system for rendering free viewpoint video from data acquired by one or more stereo camera pairs in advance. The free viewpoint video can be observed standalone or shown embedded in a synthetic computer graphics scene. Compared to state-of-the art free viewpoint video applications less cameras are required. The system is scalable in terms of adding more stereo pairs in order to increase the viewing latitude around the object and is therefore adaptable to different kinds of application such as quality assessment tasks or virtual fairs. The main contribution of this paper are i) the scalable extension of the system by additional stereo pairs and ii) the embedding of the object into a synthetic scene in a pseudo 3D manner. We implement the application using a highly customizable software framework for image processing tasks.
