Advanced motion information prediction and inheritance in 3D-HEVC

2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015
The 3D extension of High Efficiency Video Coding (3D-HEVC) is a new international video coding standard that has been developed by the Joint Collaborative Team on 3D Video Coding Extensions (JCT-3V). It aims at improving the coding efficiency of 3D and multi-view videos by introducing new coding tools to utilize the correlations between views and ...

Single depth intra coding mode in 3D-HEVC

2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015
As the state-of-the-art video coding standard, High Efficiency Video Coding (HEVC) has been finalized in January 2013. To support the coding of multiple views and associated depth data, the development of the HEVC extension for 3D video coding is also about to be finalized. New coding unit (CU) level coding tools are added to the HEVC design to improve

Complexity Reduction for Depth Map Coding in 3D-HEVC

2019
3D-HEVC is an emerging coding standard for the compression of multi-view video plus depth data. In 3D-HEVC, Depth Modeling Modes (DMMs) searching and coding unit (CU) partition consume a large proportion of the 3D-HEVC encoding complexity. This paper proposes techniques to speed up 3D-HEVC depth intra mode decision and early terminated depth CU ...

A novel distortion model for depth coding in 3D-HEVC

2014 IEEE International Conference on Image Processing (ICIP), 2014
In 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, 2014
In 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

Energy-aware scheme for the 3D-HEVC depth maps prediction

Journal of Real-Time Image Processing, 2016
This 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, 2019
This 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.

View synthesis optimization based on texture smoothness for 3D-HEVC

2015 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2015
This paper presents view synthesis optimization for 3D-HEVC based on a new texture smoothness process. In the original method, all pixels are exhaustively rendered to get distortions from synthesized views. Since not all pixels from the distorted depth map may cause distortions in the synthesized view, it brings unnecessary coding complexity.

Fast intra mode decision for depth coding in 3D-HEVC

Multidimensional Systems and Signal Processing, 2016
The emergent 3D High Efficiency Video Coding (3D-HEVC) is an extension of the High Efficiency Video Coding (HEVC) standard for the compression of the multi-view texture videos plus depth maps format. Since depth maps have different statistical properties compared to texture video, various new intra tools have been added to 3D-HEVC depth coding.
