Intra Prediction and Mode Coding in VVC [PDF]
IEEE Transactions on Circuits and Systems for Video Technology, 2021 This paper presents the intra prediction and mode coding of the Versatile Video Coding (VVC) standard. This standard was collaboratively developed by the Joint Video Experts Team (JVET). It follows the traditional architecture of a hybrid block-based codec that was also the basis of previous standards. Almost all intra prediction features of VVC either

Transforms for Intra Prediction Residuals Based on Prediction Inaccuracy Modeling [PDF]
IEEE Transactions on Image Processing, 2015 In intra video coding and image coding, the directional intra prediction is used to reduce spatial redundancy. Intra prediction residuals are encoded with transforms. In this paper, we develop transforms for directional intra prediction residuals. In particular, we observe that the directional intra prediction is most effective in smooth regions and ...

Fast Decision of Block Size, Prediction Mode, and Intra Block for H.264 Intra Prediction
IEEE Transactions on Circuits and Systems for Video Technology, 2010 The spatial-domain intra prediction scheme of H.264 has high computational complexity, especially for the High Profile as it incorporates the additional intra 8 × 8 prediction mode. To address this issue, we explore the hierarchy of H.264 mode decision process in this paper and adopt an approach that is in synchrony with the mode decision hierarchy. In
