摘要:

在过去的几十年里,随着能够编码高级语义的深度神经网络的成功,显着性预测取得了巨大的进步。然而,虽然人类有先天的能力利用他们的知识来决定看哪里(例如,人们更关注熟悉的面孔,如名人),但显着性预测模型只使用大型眼动跟踪数据集进行训练。这项工作提出了明确纳入显着性模型的外部知识,人类这样做,以弥补这一差距。我们开发的网络通过结合语义关系的先验知识来学习突出区域,无论是一般的还是特定领域的,这取决于感兴趣的任务。该方法的核心是一个新的图形语义显着性网络(GraSSNet),它构建了一个编码从外部知识中学习的语义关系的图形。然后,开发空间图形注意力网络,以基于学习的图形更新显著性特征。实验表明,该模型能够从外部知识中学习显著性预测,在四个显著性基准上的性能优于现有的显著性预测模型。

英文摘要:

The last decades have seen great progress in saliency prediction, with the success of deep neural networks that are able to encode high-level semantics. Yet, while humans have the innate capability in leveraging their knowledge to decide where to look (e.g. people pay more attention to familiar faces such as celebrities), saliency prediction models have only been trained with large eye-tracking datasets. This work proposes to bridge this gap by explicitly incorporating external knowledge for saliency models as humans do. We develop networks that learn to highlight regions by incorporating prior knowledge of semantic relationships, be it general or domain-specific, depending on the task of interest. At the core of the method is a new Graph Semantic Saliency Network (GraSSNet) that constructs a graph that encodes semantic relationships learned from external knowledge. A Spatial Graph Attention Network is then developed to update saliency features based on the learned graph. Experiments show that the proposed model learns to predict saliency from the external knowledge and outperforms the state-of-the-art on four saliency benchmarks.
