A novel distortion model for depth coding in 3D-HEVC
2014 IEEE International Conference on Image Processing (ICIP), 2014In 3D-HEVC, the latest 3D video coding project of MPEG, the coding mode of depth maps is determined by view synthesis optimization (VSO) which integrates view synthesis distortion into rate distortion optimization (RDO) to improve the compression efficiency and synthesis quality simultaneously.

Adaptive frame level rate control in 3D-HEVC
2014 IEEE Visual Communications and Image Processing Conference, 2014In this paper, we propose a new frame level rate control algorithm for the high efficiency video coding (HEVC) based 3D video (3DV) compression standard. In the proposed scheme, a new initial quantization parameter (QP) decision scheme is provided, and the bit allocation for each view is investigated to smooth the bitrate fluctuation and reach accurate

An efficient hardware solution for 3D-HEVC intra-prediction
Journal of Real-Time Image Processing, 2017Three-dimensional high-efficiency video coding (3D-HEVC) is the highest profile extension of HEVC for 3D video coding that supports the advanced 3D video format, multi-view video plus depth (MVD). Depth modelling modes (DMMs) are adopted into 3D-HEVC to preserve sharp edges and avoid ringing artefacts in synthesized views.

Modification of the merge candidate list for dependent views in 3D-HEVC
2013 IEEE International Conference on Image Processing, 2013A test model for an HEVC-based 3D video coding standard (3D-HEVC) has recently been drafted. 3D-HEVC exploits inter-view redundancies by including disparity-compensated prediction (DCP) for efficient dependent view coding. It also uses the Merge coding mode to reduce the cost of motion / disparity parameters.

Energy-aware scheme for the 3D-HEVC depth maps prediction
Journal of Real-Time Image Processing, 2016This paper presents an energy-aware scheme to reduce the energy consumption on the 3D high-efficiency video coding (3D-HEVC) depth maps prediction. Besides, a qualitative discussion is presented for intra- and inter-frame predictions that conduced to the proposition of a simple energy-aware scheme.

Security of 3D-HEVC transmission based on fusion and watermarking techniques
Multimedia Tools and Applications, 2019This paper presents two robust hybrid watermarking techniques for efficiently securing the transmission of the Three-Dimensional High Efficiency Video Coding (3D-HEVC). The first watermarking technique is the homomorphic-transform-based Singular Value Decomposition (SVD) in Discrete Wavelet Transform (DWT) domain.

3D-HEVC visual quality assessment: Database and bitstream model
2016 Eighth International Conference on Quality of Multimedia Experience (QoMEX), 2016Visual Quality Assessment of 3D/stereoscopic video (3D VQA) is significant for both quality monitoring and optimization of the existing 3D video services. In this paper, we build a 3D video database based on the latest 3D-HEVC video coding standard, to investigate the relationship among video quality, depth quality, and overall quality of experience ...
