Versatile Video Coding – Algorithms and Specification
2020 IEEE International Conference on Visual Communications and Image Processing (VCIP), 2020The tutorial provides an overview on the latest emerging video coding standard VVC (Versatile Video Coding) to be jointly published by ITU-T and ISO/IEC. It has been developed by the Joint Video Experts Team (JVET), consisting of ITU-T Study Group 16 Question 6 (known as VCEG) and ISO/IEC JTC 1/SC 29/WG 11 (known as MPEG).

Affine Intra-prediction for Versatile Video Coding
2020 28th European Signal Processing Conference (EUSIPCO), 2021New algorithms are being investigated in the context of next generation video coding to achieve higher compression efficiency. In particular, intra block copy is well known to accurately predict screen content and artificially generated content where patterns and edges may repeat within the frame.

Discrete Tchebichef Transform for Versatile Video Coding
Proceedings of the 2021 International Conference on Multimedia Retrieval, 2021The Discrete Tchebichef Transform (DTT) is a transform method based on discrete orthogonal Tchebichef polynomials, which have applications found in image compression and video coding. Our method is to construct all DTT-related discrete orthogonal transforms in the required size (corresponding to the coding unit supported by H.266/VVC).

Adaptive Resolution Change for Versatile Video Coding
2020 IEEE International Conference on Visual Communications and Image Processing (VCIP), 2020This paper presents an adaptive resolution change (ARC) method adopted in versatile video coding (VVC) to adapt the video bit-stream transmission to dynamic network environments. This approach enables resolution changes within a video sequence at any frame without the insertion of an instantaneous decoder refresh (IDR) or intra random access picture ...

Bi-Intra Prediction for Versatile Video Coding
2019 Data Compression Conference (DCC), 2019This paper presents a novel Bi-Intra Prediction (BIP) algorithm to improve intra coding performance for the next generation of video coding. In the proposed algorithm, a new predictor is generated by combining two existing intra prediction modes as an additional mode, being able to provide more accurate prediction.

Versatile Video Coding Of 360° Video Using Adaptive Resolution Change
2020 IEEE International Conference on Image Processing (ICIP), 2020Encoding 360° video with ultra high spatial resolution requires high bitrates to guarantee acceptable QoE in video delivery services. However, since in general the full Field-of-View (FoV), i.e., 360°, is not required at once, a great deal of bandwidth can be saved if only a limited FoV is delivered, according to content relevancy or/and user demand ...

Current Picture Referencing in Versatile Video Coding
2019 IEEE Conference on Multimedia Information Processing and Retrieval (MIPR), 2019Screen content coding (SCC) is a recognized feature in versatile video coding (VVC), the most recent international video coding standard development. Among all the coding tools that have been evaluated for SCC in the past, current picture referencing (CPR), or by another name intra block copy (IBC), has shown its effectiveness in coding of computer ...

Multi-frame super-resolution for versatile video coding
International Workshop on Advanced Imaging Technology (IWAIT) 2021, 2021The latest video coding standard, Versatile Video Coding (VVC), has been finalized in July 2020. In traditional codecs, it is not possible to refer to different resolution pictures in inter-picture prediction except for inter layer cases. However, VVC does support Reference Picture Resampling (RPR), which allows pictures to refer to different ...
