Venkatesh Department of Electrical Engineering, Indian Institute of Technology, Hauz Khas, Delhi 110016, India article info Article history: Available online 27 July 2013 Keywords: Depth image based rendering Multi-view 3DTV Content based view speci?cation Free-viewpoint video View synthesis Hole-?lling Arbitrary virtual view rendering Uncalibrated cameras Selective warping abstract This paper presents a novel ?exible architecture for 3DTV based on multiple uncalibrated cameras. The proposed signal representation improves the interactivity of dense point-based methods, making them appropriate for modeling the scene semantics and free-viewpoint 3DTV applications. The main concern is to address the shortcomings of depth image-based 3D video systems for free-viewpoint visualization, and to provide an ef?cient implementation of the rendering part which is computationally intensive as well potentially determine the view quality. Novel rendering algorithms are added that speci?cally aim at solving the rendering artifacts, and sampling issues encountered in wide baseline extensions and arbitrary camera movements. To optimize the process, a ‘‘selective’’ warping technique is proposed that takes the advantage of temporal coherence to reduce the computational overhead. Performance is illustrated on challenging videos to prove the suitability and ?exibility of the architecture for advanced 3DTV systems. ó 2013 Elsevier Inc. All rights reserved. 1.
