Saliency Map Incorporating Attractiveness of Moving Object to Estimate Human Driver's Potential Gaze Area

Abstract

The present paper proposes a computational model of the human drivers’ vision named “moving object attractiveness map”, aiming at image processing technique to analyze unsafe traffic conditions that may provoke their inappropriate allocation of visual attention. Saliency map is a computational model of image processing to simulate human visual attention after scientific findings of bottom-up information processing at the low-level visual cortex, which extracts distributions of salience features from a given image and combines them to estimate which areas in the image can attract the observer’s visual attention more. The proposed model adds a top-down attention filter to the saliency map that predicts the likelihood of visual objects to attract the observer’s attention for possible collisions.
