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


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.
