HEVC-based 3D holoscopic video coding using self-similarity compensated prediction
TL;DR: The proposed 3D holoscopic codec makes use of the self-similarity (SS) compensated prediction concept to efficiently explore the inherent correlation of the 3D Holoscopic content in Intra- and Inter-coded frames, as well as a novel vector prediction scheme to take advantage of the peculiar characteristics of the SS prediction data.
Proceedings ArticleDOI
HEVC-based light field image coding with bi-predicted self-similarity compensation
TL;DR: An efficient light field image coding (LFC) solution based on High Efficiency Video Coding (HEVC) that makes use of the self-similarity (SS) compensated prediction concept to efficiently explore the inherent correlation of this type of content is proposed.

TL;DR: This paper proposes the addition of two new prediction tools to the HEVC framework, to improve its coding efficiency and based on the local linear embedding-based prediction and the self-similarity compensated prediction.
Proceedings ArticleDOI
New HEVC prediction modes for 3D holoscopic video coding
TL;DR: Experimental results, based on the HEVC test model version 4.0 are presented and clearly show the advantages of using new prediction modes in HEVC to explore the particular structure of 3D holoscopic content, in order to further improve the performance of HEVC for this type of content.
