RD-cost Regression Speed Up Technique for VVC Intra Block Partitioning

Résumé

The last standard Versatile Video Codec (VVC) aims to improve the compression efficiency by saving around 50% of bitrate at the same quality compared to its predecessor High Efficiency Video Codec (HEVC). However, this comes with higher encoding complexity mainly due to a much larger number of block splits to be tested on the encoder side. This paper proposes an acceleration of the VVC partitioning based on a multi-output regression model that predicts a suitable split mode for 32 × 32 Coding Unit (CU). Experimental results show that our approach improves complexity trade-offs flexibility while adding better complexity trade-offs points compared to the original encoder.
