Comparative analysis of three different modalities for perception of artifacts in videos

This study compares three popular modalities for analyzing perceived video quality; user ratings, eye tracking and EEG.

We contrast these three modalities for a given video sequence to determine if there is a gap between what humans consciously see and what we implicitly perceive. Participants are shown a video sequence with different artifacts appearing at specific distances in their field of vision; near foveal, middle peripheral and far peripheral.

Our results show distinct differences between what we saccade to (eye-tracking), how we consciously rate video quality and our neural responses (EEG data). Our findings indicate that the measurement of perceived quality depends on the specific modality used.
