Abstract

It is vital that video encoders remove redundant information present in the spherically projected 360° video frames. To this end, this paper proposes a novel weighted residual technique and an integrated technique between the proposed weighted residual technique and a state-of-the-art adaptive quantization technique. The proposed methods adapt to the spherical characteristics in order to reduce the magnitude of the redundant information. The tests of the weighted residual technique and the integrated technique with All-Intra configuration using Versatile Video Coding (VVC) test model, produce average bit rate savings between 0.91% and 1.35% with regards to various spherical objective quality metrics.
