On the First JND and Break in Presence of 360-degree Content: An Exploratory Study. Azevedo, R. G. d. A., Birkbeck, N., Janatra, I., Adsumilli, B., & Frossard, P. In Proceedings of the 11th ACM Workshop on Immersive Mixed and Virtual Environment Systems, of MMVE '19, pages 1–3, New York, NY, USA, 2019. ACM.
Paper doi abstract bibtex 45 downloads Unlike traditional planar 2D visual content, immersive 360-degree images and videos undergo particular processing steps and are intended to be consumed via head-mounted displays (HMDs). To get a deeper understanding on the perception of 360-degree visual distortions when consumed through HMDs, we perform an exploratory task-based subjective study in which we have asked subjects to define the first noticeable difference and break-in-presence points when incrementally adding specific compression artifacts. The results of our study: give insights on the range of allowed visual distortions for 360-degree content; show that the added visual distortions are more tolerable in mono than in stereoscopic 3D; and identify issues with current 360-degree objective quality metrics.
