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

Abstract

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 with the original HEVC algorithms in the depth map intra-frame prediction for allowing high-efficiency encoding. Besides, this paper analyzes the encoding time and the encoding mode distribution of the intra-frame prediction tools over different quantization scenarios. We aim to provide support for upcoming works on depth map encoding, including complexity reduction and control, real-time embedded systems implementations, and even the development of improved tools to encode depth maps.

A Bit Allocation Method Based on Proportional-Integral-Derivative Algorithm for 3DTV

“…At present, most domestic and foreign research on rate control is based on H.264, HEVC, MVC, and 3D-HEVC [10][11][12][13][14]. The research on MV-HEVC is not as good as that on the other rate control technologies.…”

Texture-Guided End-to-End Depth Map Compression

“…Depth Modeling Modes (DMMs) [5] were introduced to preserve the depth edges by modeling the edge information in depth blocks. Depth Wedge and Contour (D-WC) [6,7] was proposed to adopt plane fitting for the large smooth areas and non-rectangular cutting for the sharp edges. Although these techniques are integrated into 3D-HEVC [8], the characteristics of the depth map are still left insufficiently explored since the core of 3D-HEVC is inherited from HEVC [9], which is designed for the texture image.…”

Latent Factor Modeling of Perceived Quality for Stereoscopic 3D Video Recommendation

“…The study conducted by Barreda et al [10] on 3D contents using psycho-physiological methods determined complex effects of visual discomfort regarding 3DTV, which may cause headache, nausea, fatigue, eye strain, etc. According to several publications, the compression artefacts and their variations (based on the depth range of 3D displays) may noticeably affect the perception of the viewers [11][12][13][14]. Furthermore, multiple studies conclude that discomfort is greater for certain types of distortions than for others when viewing S3D contents, and that the influence primarily originates from the content itself.…”
