360-DEGREE VIDEO QUALITY EVALUATION

360-degree video is emerging as a new way of offering immersive visual experience. The quality evaluation of 360-degree video is more difficult compared to the quality evaluation of conventional video. However, to ensure successful development of 360-degree video coding technologies, it is essential to precisely measure both objective and subjective quality. In this paper, an overview of the 360-degree video quality evaluation framework established by the joint video exploration team (JVET) of ITU-T VCEG and ISO/IEC MPEG is provided. This framework aims at reproducing the different processes in the 360-degree video processing workflow that are related to coding. The results of different experiments conducted using the JVET framework are reported to illustrate the impact on objective and subjective quality with different projection formats and codecs.
