An Effectiveness Evaluation of RoI Boundary Smoothing in Omnidirectional Video Streaming

Abstract

Some efficient 360-degree omnidirectional video streaming methods are in the market these days. In general the methods make it possible to stream the video in a limited network bandwidth by sending a part, user’s RoI (Region of Interest), of the video. However, it can impair user’s QoE (Quality of Experience) due to quality discontinuity of the image at the RoI boundary section. In this paper, we propose a method that can mitigate the discontinuity and improve the QoE by smoothing the section. Subjective evaluation results are also shown.
