• Title: Object-aware Gaze Target Detection
• Authors: Francesco Tonini and Nicola Dall'Asen and Cigdem Beyan and Elisa Ricci
• Abstract summary: This paper proposes a Transformer-based architecture that automatically detects objects in the scene to build associations between every head and the gazed-head/object. Our method achieves state-of-the-art results on all metrics for gaze target detection and 11-13% improvement in average precision for the classification and the localization of the gazed-objects.

• Abstract: 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 overlooked decoding the relationship between the people and the gazed objects. This paper proposes a Transformer-based architecture that automatically detects objects (including heads) in the scene to build associations between every head and the gazed-head/object, resulting in a comprehensive, explainable gaze analysis composed of: gaze target area, gaze pixel point, the class and the image location of the gazed-object. Upon evaluation of the in-the-wild benchmarks, our method achieves state-of-the-art results on all metrics (up to 2.91% gain in AUC, 50% reduction in gaze distance, and 9% gain in out-of-frame average precision) for gaze target detection and 11-13% improvement in average precision for the classification and the localization of the gazed-objects. The code of the proposed method is publicly available.

  This paper presents a more challenging gaze object segmentation (GOS) task, which involves inferring the pixel-level mask corresponding to the object captured by human gaze behavior. We propose to automatically obtain head features from scene features to ensure the model's inference efficiency and flexibility in the real world.

  Training agents to manipulate objects, poses many challenges. We propose an approach that explores the environment in search for target objects, computes their 3D coordinates once they are located, and then continues to estimate their 3D locations even when the objects are not visible. Our evaluations show a massive 3x improvement in success rate over a model that has access to the same sensory suite.
