An active foveated gaze prediction algorithm based on a Bayesian ideal observer

Abstract

Predicting human eye movements is a crucial task for understanding human behavior and has numerous applications in machine vision. Most current models for predicting eye movements are data-driven and require large datasets of recorded eye movements, which can be expensive and time-consuming to collect. In this paper, we present a novel theory-based model for predicting eye movements in a foveated visual system that maximizes information gain at each fixation. Our model uses a region-proposal network and eccentricity-based max pooling to account for the loss of detail in peripheral vision. We apply our model to predict human fixations in a visual search task for objects in real-world scenes. ..
