Imbalanced Splitting Depth Level for 3D-HEVC Transcoding

2018 IEEE 3rd International Conference on Image, Vision and Computing (ICIVC), 2018
As an emerging video codec standard for multi-view video and corresponding depth maps, three-dimensional extension of High Efficiency Video Coding (3D-HEVC) has broad application prospect. In order to make the bit-stream generated by 3D-HEVC suitable for emerging terminal devices, reducing computational complexity is necessary for downsizing resolution

Advanced texture and depth coding in 3D-HEVC

Journal of Visual Communication and Image Representation, 2018
Abstract The 3D extension of High Efficiency Video Coding (3D-HEVC) is a new international video coding standard developed by the Joint Collaborative Team on 3D Video Coding Extensions (JCT-3V) in order to support coding of multiple views and its associated depth data.

3D-HEVC depth maps intra prediction complexity analysis

2016 IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2016
This paper presents a complexity analysis of 3D High Efficiency Video Coding (3D-HEVC) depth maps intra prediction. The 3D-HEVC inserts new coding tools in depth maps intra prediction such as Depth Intra Skip (DIS), Depth Modeling Modes (DMMs) and Segment-wise DC (SDC). Therefore, it is important to understand the complexity of each module to allow the

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

Unified wedgelet genenration for depth coding in 3D-HEVC

2014 IEEE International Conference on Image Processing (ICIP), 2014
In 3D-HEVC, bi-partition based modes, i.e., depth modeling modes (DMM), are applied for depth intra coding. With DMM, a depth prediction unit (PU) is partitioned into two parts using a Wedgelet pattern selected from a predefined large Wedgelet set, and the Wedgelet set is generated during both encoder and decoder initialization for each block size ...

High-Throughput Hardware Design for 3D-HEVC Disparity Estimation

IEEE Design & Test, 2020
Editor’s note : Disparity refers to the fact, that, for example, human beings see an object from a different angle with the left eye and the right eye. The disparity es-timation in images produces a computationally intensive effort. The HEVC disparity estimation can be analyzed according to its efficient implementa-tion and high throughput.

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 ...

Fast wedgelet pattern decision for DMM in 3D-HEVC

2015 IEEE International Conference on Digital Signal Processing (DSP), 2015
3D-HEVC is in the process of standardization as the highest profile extension of HEVC for 3D video coding, which supports the advanced 3D video format, namely multi-view videos plus depth (MVD). In order to preserve the sharp edges and avoid the ringing artifacts in the synthesized views, depth modelling modes (DMMs) are adopted into 3D-HEVC to achieve

Fast 3D-HEVC Depth Map Encoding Using Machine Learning

IEEE Transactions on Circuits and Systems for Video Technology, 2020
This paper presents a fast depth map encoding for 3D-High Efficiency Video Coding (3D-HEVC) based on static decision trees. We used data mining and machine learning to correlate the encoder context attributes, building the static decision trees. Each decision tree defines that a depth map Coding Unit (CU) must be or not be split into smaller blocks ...

3D-HEVC visual quality assessment: Database and bitstream model

2016 Eighth International Conference on Quality of Multimedia Experience (QoMEX), 2016
Visual 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 ...
