Stereoscopic Video Coding for Mobile Applications

After considering the growing demand for realistic video reproduction, in this thesis, we have proposed two stereoscopic video coding schemes that are evaluated for the suitability for 3D mobile applications. One is an H.264 based stereoscopic video codec and the other is a Distributed Video Coding (DVC) based stereoscopic codec. First, we propose an H.264 based stereoscopic codec that includes a modification to handle two video streams in order to exploit disparity and worldline correlations as well as a design of a novel motion/disparity vector prediction algorithm that operates more intelligently using the previously coded motion/disparity vectors. Secondly, we have designed several algorithms to improve the coding efficiency of Wyner-Ziv frames and a novel algorithm for key frame coding in DVC. These algorithms include a spatial and temporal correlation exploitation algorithm for side information generation, a multiple side information handling algorithm and a bitplane by bitplane refinement technique in addition to the DVC based key frame coding scheme. Finally this thesis, presents a W-CDMA channel simulation for both proposed stereoscopic codecs.
