Fixation Prediction for 360° Video Streaming in Head-Mounted Virtual Reality
NOSSDAV'17: Proceedings of the 27th Workshop on Network and Operating Systems Support for Digital Audio and VideoPages 67–72https://doi.org/10.1145/3083165.3083180We study the problem of predicting the Field-of-Views (FoVs) of viewers watching 360° videos using commodity Head-Mounted Displays (HMDs). Existing solutions either use the viewer's current orientation to approximate the FoVs in the future, or ...
