Title
Luma-Aware Multi-Model Rate-Control For Hdr Content In Hevc
Abstract
Rate control (RC) is an important tool that helps to control the bit rate of the compressed media. Current HEVC implementations include an RC algorithm, based on a R - lambda model, that does not consider the wide range of luma values depicted in HDR content. This paper proposes a multi-R - lambda-model approach for RC in HEVC that accurately attains a target bit rate while improving the reconstruction quality of HDR content, especially for very bright regions. Results, in terms of the mP-SNR and HDR-VDP-2 metrics, confirm the advantages of our approach compared to the current RC algorithm in HEVC.
