A New Regularization For Retinex Decomposition of Low-Light Images

independently coding areas in a video have potential for improved coding efficiency in Region-of-interest (RoI) streaming applications where clients can freely switch between RoI and full view streams. This paper investigates three schemes for RoI coding in streaming scenarios based on VVC to enable harnessing open GOP coding efficiency gains. Two schemes are based on Motion-Constrained-Tile-Sets while a third scheme relies on the new VVC feature referred to as independent subpictures. The reported results show substantial bitrate gains for the RoI streams compared to na�ve closed-GOP coding of up to -8.68% YUV BD-rate while for the full stream minor coding efficiency losses are reported.
