A Framework for Adaptive Delivery of Omnidirectional Video [PDF]
IS&T International Symposium on Electronic Imaging, 2018 Omnidirectional or 360-degree videos are considered as a next step towards a truly immersive media experience. Such videos allow the user to change her/his viewing direction while consuming the video. The download-and-play paradigm (including DVD and Blu-ray) is replaced by streaming, and the content is hosted solely within the cloud.

Recent Advances in Saliency Estimation for Omnidirectional Images, Image Groups, and Video Sequences
Applied Sciences, 2020 We present a review of methods for automatic estimation of visual saliency: the perceptual property that makes specific elements in a scene stand out and grab the attention of the viewer.

Novel tile segmentation scheme for omnidirectional video [PDF]
2016 IEEE International Conference on Image Processing (ICIP), 2016 Regular omnidirectional video encoding technics use map projection to flatten a scene from a spherical shape into one or several 2D shapes. Common projection methods including equirectangular and cubic projection have varying levels of interpolation that create a large number of non-information-carrying pixels that lead to wasted bitrate. In this paper,

Retina-based quality assessment of tile-coded 360-degree videos
EAI Endorsed Transactions on Industrial Networks and Intelligent Systems, 2022 Nowadays, omnidirectional content, which delivers 360-degree views of scenes, is a significant aspect of Virtual Reality systems. While 360 video requires a lot of bandwidth, users only see visible tiles, therefore a large amount of bitrate can be saved

Multi-Feature 360 Video Quality Estimation
IEEE Open Journal of Circuits and Systems, 2021 We propose a new method for the visual quality assessment of 360-degree (omnidirectional) videos. The proposed method is based on computing multiple spatio-temporal objective quality features on viewports extracted from 360-degree videos.

Audio-Visual Saliency for Omnidirectional Videos
, 2023 Visual saliency prediction for omnidirectional videos (ODVs) has shown great significance and necessity for omnidirectional videos to help ODV coding, ODV transmission, ODV rendering, etc.. However, most studies only consider visual information for ODV saliency prediction while audio is rarely considered despite its significant influence on the viewing

Foveation Pipeline for 360° Video-Based Telemedicine
Sensors, 2020 Pan-tilt-zoom (PTZ) and omnidirectional cameras serve as a video-mediated communication interface for telemedicine. Most cases use either PTZ or omnidirectional cameras exclusively; even when used together, images from the two are shown separately on 2D ...
