Using pupillary response to assess video quality
Deepti Pappusetty, Vishnu Vardhan Reddy Chinta, Hari Kalva · 2017
Pupil response can be measured non-intrusively using an eye tracker and offers a potentially new approach to understanding video structure and content. An analysis of pupil response to quality variations in a video is reported in this paper. Experiments were conducted under free viewing conditions and pupillary response of subjects was analyzed. Video clip encoded with AVC/H.264 at various qualities and durations were used to assess user response. Results show pupillary constrictions at points of quality transitions.
