Image features and eye movements

Abstract

The human visual system processes retinal input images to extract information that is useful for living. The eye movement control is one of the functions of the information extracting system and there should be close relationship between positions of eye fixation and image features. In this study, we measured observer's eye movements for free viewing natural images to investigate the relationship. Fixation duration varied between shorter than 100ms and longer than 1s. We investigated how fixation duration is related to the image features with a feature map analysis.
