Face perception: Influence of location and number in videos

Abstract

The study is about the influence of face in videos. In the experiment, the participants were instructed free viewing of various videos. The resulting eye positions are compared to the hand-labeled faces to evaluate the impact of location and number of faces in the visual field. Here, we defined three regions - Inside (I), Periphery (P), and Outside (O) - to categorize video frames with one or two faces based on the location of faces. Then we perform the evaluation of all these categories to get resulting scores. The scores indicate that the impact of face is a function of its eccentricity such that it falls as the face is far from the center of the visual scene. Similarly, the number of faces also limits face attraction.
