Abstract :
SECOND-MVD (Synthesis Error COmpeNsateD Multiview Video plus Depth) is an alternative 3D format that we introduce for representation of multiview video. In this data format, images at some viewpoint remain original, and the others are converted to a novel format. Residual based representation, such as layered depth video and free-viewpoint TV data unit were proposed. We propose hybrid image that not only consists of residual but also remainder pixels. Generation and reconstruction process of a hybrid image uses virtual image synthesized by the images that remained original in SECOND-MVD. In this paper, we investigate the compression performance of SECOND-MVD using hybrid image. Experiments demonstrate reduction in bit rate using hybrid image against residual image in SECOND-MVD framework.
