    (2010) Congote, John; Barandiaran, Iñigo; Barandiaran, Javier; Montserrat, Tomas; Quelen, Julien; Ferran, Christian; Mindan, Pere J.; Mur, Olga; Tarres, Francesc; Ruíz, Óscar; Universidad EAFIT. Departamento de Ingeniería Mecánica; Laboratorio CAD/CAM/CAE
    In this paper we present a reliable depth estimation system which works in real-time with commodity hardware -- The system is specially intended for 3D visualization using autostereoscopic displays -- The core of this work is an implementation of a modifed version of the adaptive support-weight algorithm that includes highly optimized algorithms for GPU, allowing accurate and stable depth map generation -- Our approach overcomes typical problems of live depth estimation systems such as depth noise and ickering -- Proposed approach is integrated within the versatile GStreamer multimedia software platform -- Accurate depth map estimation together with real-time performance make proposed approach suitable for 3D videoconferencing

    This paper presents the implementation of a high quality real-time 3D video system intended for 3D videoconferencing -- Basically, the system is able to extract depth information from a pair of images coming from a short-baseline camera setup -- The system is based on the use of a variant of the adaptive support-weight algorithm to be applied on GPU-based architectures -- The reason to do it is to get real-time results without compromising accuracy and also to reduce costs by using commodity hardware -- The complete system runs over the GStreamer multimedia software platform to make it even more flexible -- Moreover, an autoestereoscopic display has been used as the end-up terminal for 3D content visualization
