A Comparison of Different Side Information Generation Methods for Multiview Distributed Video Coding

This paper presents a comparison of the performance of different side information generation methods for multiview distributed video coding scenarios. Existing literature on this topic relies on pure temporal interpolation (by means of motion compensation), pure inter-camera interpolation (by means of disparity compensation) or a combination of both. In this work a different approach is used by calculating the motion vectors on an available conventionally-encoded camera (one that is not encoded using distributed principles) and then using the obtained motion vectors to generate the side information for the camera that requires it. Variations of this technique are also presented, along with a mechanism to merge all of them together. Finally, simulation results comparing with other techniques and conclusions are given.
