Dominance of Perceptual Grouping over Functional Category: An Eye Tracking Study of High Resolution Satellite Images

摘要

The presented study is an attempt to determine the object grouping propensity of human visual system for further human-like analysis of High-Resolution Satellite (HRS) image by using an eye tracker. Perception, which is a basic characteristic of the human visual system, enables to part the visual stimuli into meaningful parts. This parting is either based on perceptual or functional grouping. However, these perceptual groups are often different from functional categories. All objects from one functional category are perceived equivalent, irrespective of their physical appearance variation. The recent advancements in eye tracking technology have provided an excellent modality to articulate the eye movement data with inner psychological factors. In this way, the presented study has exploited the fixation data to understand the perceptual organization for HRS images. The outcomes of this study has provided the analytical solution for grouping tendency of humans along with the heat maps as evidence.
