Learning Compressible 360{\deg} Video Isomers
Standard video encoders developed for conventional narrow field-of-view video are widely applied to 360° video as well, with reasonable results. However, while this approach commits arbitrarily to a projection of the spherical frames, we observe that some orientations of a 360° video, once projected, are more compressible than others. We introduce an approach to predict the sphere rotation that...
متن کاملVirtual displays for 360-degree video
In this paper we describe a novel approach for comparing users' spatial cognition when using different depictions of 360degree video on a traditional 2D display. By using virtual cameras within a game engine and texture mapping of these camera feeds to an arbitrary shape, we were able to offer users a 360-degree interface composed of four 90-degree views, two 180-degree views, or one 360-degree...
متن کاملAnalysis of 360° Video Viewing Behaviours
In recent years there has been a significant interest in Virtual Reality applications, including 360° videos. 360° video streaming via the network typically consumes a lot of bandwidth due to the file size of these kind of videos being up to 6 times larger than traditional videos. Due to the nature of 360° videos, a user only utilizes about 20 % of the transmitted data; that is, the part of the...
متن کامل360-Degree Video Head Movement Dataset
While Virtual Reality applications are increasingly attracting the attention of developers and business analysts, the behaviour of users watching 360-degree (i.e. omnidirectional) videos has not been thoroughly studied yet. This paper introduces a dataset of head movements of users watching 360-degree videos on a Head-Mounted Display (HMD). The dataset includes data collected from 59 users watc...
متن کاملMaking 360° Video Watchable in 2D: Learning Videography for Click Free Viewing
360° video requires human viewers to actively control “where” to look while watching the video. Although it provides a more immersive experience of the visual content, it also introduces additional burden for viewers; awkward interfaces to navigate the video lead to suboptimal viewing experiences. Virtual cinematography is an appealing direction to remedy these problems, but conventional method...
