摘要:

人类情感行为分析在人机交互系统中起着至关重要的作用。在本文中,我们介绍了我们提交的CVPR 2023年情感行为分析比赛(ABAW)。我们提出了一个单阶段训练的AU检测框架。具体来说,为了有效地提取与AU检测相关的面部局部区域特征,我们使用局部区域感知模块来有效地提取不同AU的特征。同时,我们使用一个基于图神经网络的关系学习模块来捕捉AU之间的关系。此外,考虑到目标人脸的整体特征对AU检测的作用,我们还利用特征融合模块对骨干网络提取的特征信息和关系学习模块提取的AU特征信息进行融合。我们还采用了一些抽样方法、数据增强技术和后处理策略来进一步提高模型的性能。

英文摘要:

Human affective behavior analysis plays a vital role in human-computer interaction (HCI) systems. In this paper, we introduce our submission to the CVPR 2023 Competition on Affective Behavior Analysis in-the-wild (ABAW). We propose a single-stage trained AU detection framework. Specifically, in order to effectively extract facial local region features related to AU detection, we use a local region perception module to effectively extract features of different AUs. Meanwhile, we use a graph neural network-based relational learning module to capture the relationship between AUs. In addition, considering the role of the overall feature of the target face on AU detection, we also use the feature fusion module to fuse the feature information extracted by the backbone network and the AU feature information extracted by the relationship learning module. We also adopted some sampling methods, data augmentation techniques and post-processing strategies to further improve the performance of the model.
