GazeHRNet: Head-Centric Spatial Encoding and Gaze-Aware Feature Interaction for Gaze Target Detection

GazeHRNet is proposed, a head-centric reasoning framework for RGB-based gaze target detection that combines coarse spatial reasoning with fine-grained anisotropic heatmap prediction, enabling reliable target localization under cluttered scenes and varying head positions.
