 # PolyCAT: Polygon-Aperture Eye-Tracking Dataset
 
 PolyCAT is a public eye-tracking dataset for studying visual attention on natural images viewed through irregular polygon apertures. The dataset is designed to support saliency prediction, gaze modeling, and research on how geometric viewing constraints affect visual exploration strategies.
