2021 Picture Coding Symposium (PCS), 2021
The paper describes the novel aspects of deblocking filter in VVC. We demonstrate the insufficiency of HEVC deblocking filter when employing larger transform block sizes and describe the design changes made to enable reduction of the resulting blocking artifacts for both luma and chroma, while also allowing for parallel friendly processing ...

Adaptive Color Transform in VVC Standard
2020 IEEE International Conference on Visual Communications and Image Processing (VCIP), 2020This paper provides an in-depth overview of the adaptive color transform (ACT) tool that is adopted into the emerging versatile video coding (VVC) standard. With the ACT, prediction residuals in the original color space are adaptively converted into another color space to reduce the correlation among the three color components of video sequences in 4:4:

Sparse Coding-based Intra Prediction in VVC
2021 Picture Coding Symposium (PCS), 2021Intra prediction is crucial to video coding as it is the only option for prediction when motion compensation either fails or no reference frames are available. Hence, current state-of-the-art video coding standards utilize numerous intra prediction modes in order to predict different angled structures as well as smooth areas.
