Perceptual Asymmetric Video Coding for 3D-HEVC

2016
In the scope of stereoscopic 3D video, asymmetric video coding is an effective method in terms of maintaining the perceived quality while reducing the required transmission bandwidth by exploiting the perceptual phenomenon of binocular suppression. On the other hand, just noticeable distortion (JND) has been applied successfully in improving the video ...

Performance Analysis of Depth Intra-Coding in 3D-HEVC

IEEE Transactions on Circuits and Systems for Video Technology, 2019
The depth maps intra-frame prediction of 3D High Efficiency Video Coding (3D-HEVC) inherits all texture encoding techniques provided by HEVC and provides new coding tools for depth map predictions. These tools comprise algorithms, such as bipartition modes, intra-picture skip, and DC-only. This paper details these tools and shows how they work together

Complexity and compression efficiency assessment of 3D-HEVC encoder

Multimedia Tools and Applications, 2020
This paper presents a complexity and compression efficiency assessment of the 3D-High Efficiency Video Coding (3D-HEVC) encoder. An experimental evaluation was carried out to identify the encoding tools with the highest impact on the computational complexity of 3D-HEVC.

Texture mode dependent depth coding in 3D-HEVC

2013 IEEE International Conference on Image Processing, 2013
In 3D-HEVC, depth modeling modes (DMM) are applied for efficient intra depth coding. With DMM modes, a prediction unit is partitioned into two parts, and each part is predicted by a single value. In one DMM mode, the partition pattern is implicitly derived at the decoder by searching all pre-defined Wedgelet patterns on a Co-located Texture Luma Block (

Modification of the disparity vector derivation process in 3D-HEVC

2013 IEEE 15th International Workshop on Multimedia Signal Processing (MMSP), 2013
The up-and-coming extension of HEVC for 3D video (3D-HEVC) includes various tools to exploit different redundancies in a 3D video signal. Inter-view redundancies are in particular exploited using Inter-View Motion Prediction (IVMP) and Inter-View Residual Prediction (IVRP).

A low-latency DMM-1 encoder for 3D-HEVC

Journal of Real-Time Image Processing, 2019
Depth modeling mode 1 (DMM-1) is vital for 3D high-efficiency video coding, since it results in low distortion and is suitable for sharp boundaries. When designing DMM-1 encoders, traditional work used serial methods to calculate all the wedgelets, leading to large latency; they may meet the requirements of 30 fps 1080P 3D video at most, but may be ...

Simplified inter-component depth modeling in 3D-HEVC

IVMSP 2013, 2013
In this paper, we present a method to reduce complexity of depth modeling modes (DMM), which is currently used in the 3D-HEVC standardization activity. DMM adds four modes to the existing HEVC intra prediction modes; the main purpose is to accurately represent object edges in depth video. Mode 3 of DMM requires distortion calculation of all pre-defined

Improved LCU level rate control for 3D-HEVC

2016 Visual Communications and Image Processing (VCIP), 2016
In this paper, we propose an improved Largest Coding Unit (LCU) level rate control algorithm for the 3D video coding extension of the high efficiency video coding (3D-HEVC). In the proposed algorithm, bit allocation for extended views is investigated in combination with temporal and inter-view Mean Absolute Difference (MAD) predictions. Upon prediction

Complexity reduction for the 3D-HEVC depth maps coding

2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015
This paper presents a qualitative discussion of the depth maps properties that can be considered to achieve complexity reduction for 3D-High Efficiency Video Coding (3D-HEVC) depth maps coding. Both intra and inter-frame predictions are considered in this discussion that conduced to the proposition of two simple complexity reduction techniques: the ...

Fast encoder decision for texture coding in 3D-HEVC

Signal Processing: Image Communication, 2014
As a 3D extension of the High Efficiency Video Coding (HEVC) standard, 3D-HEVC is developed to improve the coding efficiency of multi-view video. However, the improvement of the coding efficiency is obtained at the expense of a computational complexity increase.
