Object-aware Gaze Target Detection [PDF]

open access: yesIEEE International Conference on Computer Vision, 2023
Gaze target detection aims to predict the image location where the person is looking and the probability that a gaze is out of the scene. Several works have tackled this task by regressing a gaze heatmap centered on the gaze location, however, they ...
