Adaptive Resolution Change for Versatile Video Coding

2020 IEEE International Conference on Visual Communications and Image Processing (VCIP), 2020
This 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 ...

Optimized Adaptive Loop Filter in Versatile Video Coding

2021 Data Compression Conference (DCC), 2021
In the Versatile Video Coding (VVC) standard, adaptive loop filter (ALF), including Geometry transformation-based Adaptive Loop Filter (GALF) and Cross Component Adaptive Loop Filter (CCALF), plays an essential role in reducing compression artifacts. However, it also has high coding complexity and requires many picture buffer accesses in the encoder ...

Edge-Directed Geometric Partitioning For Versatile Video Coding

2020 IEEE International Conference on Multimedia and Expo (ICME), 2020
To improve the coding performance, geometric partition (GEO) was proposed for the upcoming VVC standard. GEO provides 140 partition candidates. The index of optimal GEO mode needs to be signaled explicitly. Considering different structural characteristics of different CUs and the correlation between spatial adjacent blocks and temporal collocated ...
