摘要:

注视目标预测(GOP)旨在预测人类正在注视的物体的类别和位置。以往方法利用框级监督来识别人正在注视的物体,但由于物体彼此靠近,单个框可能包含多个物品,因此在语义歧义方面存在困难。视觉基础模型(VFM)在使用框提示进行物体分割方面取得了进展,可以通过更精确地定位物体来减少混淆,为注视目标的细粒度预测提供了优势。本文提出了一个更具挑战性的注视目标分割(GOS)任务,该任务涉及推断与人类注视行为所捕获的物体相对应的像素级掩码。特别是,我们提出可以将VFM提供的像素级监督整合到注视目标预测中,以缓解语义歧义。由此形成了我们的注视目标检测与分割框架,能够实现准确的像素级预测。与以往需要额外头部输入或忽略头部特征的方法不同,我们提出从场景特征中自动获取头部特征,以确保模型在现实世界中的推理效率和灵活性。此外,不同于现有方法直接融合特征来预测注视热图,这可能会忽略物体的空间位置和细微细节,我们开发了一种空间到物体的注视回归方法,以促进人-物注视交互。具体来说,它首先构建初始的人-物空间连接,然后通过与分割分支中语义清晰的特征进行交互来细化该连接,最终预测注视热图以实现精确定位。在GOO-Synth和GOO-Real数据集上的大量实验证明了我们方法的有效性。

英文摘要:

Gaze object prediction (GOP) aims to predict the category and location of the object that a human is looking at. Previous methods utilized box-level supervision to identify the object that a person is looking at, but struggled with semantic ambiguity, ie, a single box may contain several items since objects are close together. The Vision foundation model (VFM) has improved in object segmentation using box prompts, which can reduce confusion by more precisely locating objects, offering advantages for fine-grained prediction of gaze objects. 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. In particular, we propose that the pixel-level supervision provided by VFM can be integrated into gaze object prediction to mitigate semantic ambiguity. This leads to our gaze object detection and segmentation framework that enables accurate pixel-level predictions. Different from previous methods that require additional head input or ignore head features, we propose to automatically obtain head features from scene features to ensure the model's inference efficiency and flexibility in the real world. Moreover, rather than directly fuse features to predict gaze heatmap as in existing methods, which may overlook spatial location and subtle details of the object, we develop a space-to-object gaze regression method to facilitate human-object gaze interaction. Specifically, it first constructs an initial human-object spatial connection, then refines this connection by interacting with semantically clear features in the segmentation branch, ultimately predicting a gaze heatmap for precise localization. Extensive experiments on GOO-Synth and GOO-Real datasets demonstrate the effectiveness of our method.
