A Computational–Cognitive Model of Audio-Visual Attention in Dynamic Environments

Year: 2025

Type: article

Abstract: Human visual attention is influenced by multiple factors, including visual, auditory, and facial cues. While integrating auditory and visual information enhances prediction accuracy, many existing models rely solely on visual-temporal data. Inspired by cognitive studies, we propose a computational model that combines spatial, temporal, face (low-level and high-level visual cues), and auditory saliency to predict visual attention more effectively. Our approach processes video frames to generate spatial, temporal, and face saliency maps, while an audio branch localizes sound-producing objects. These maps are then integrated to form the final audio-visual saliency map. Experimental results on the audio-visual dataset demonstrate that our model outperforms state-of-the-art image and video saliency models and the basic model and aligns more closely with behavioral and eye-tracking data. Additionally, ablation studies highlight the contribution of each information source to the final prediction.
