摘要:

在过去的几年里,面部识别/识别已经有了显著的进步。然而,大多数提出的方法依赖于静态RGB帧和中性面部表情。这有两个缺点。首先,重要的面部形状线索被忽略了。第二,由于表情的面部变形可能会影响这种方法的性能。在本文中,我们提出了一个新的框架,动态三维人脸识别/识别的基础上面部关键点。每个动态序列的面部表情表示为时空图,这是使用3D面部地标构造。每个图节点包含从其邻域提取的局部形状和纹理特征。对于面部的分类/识别,使用时空图卷积网络(ST-GCN)。最后,我们评估我们的方法上具有挑战性的动态3D面部表情数据集。

英文摘要:

Face identification/recognition has significantly advanced over the past years. However, most of the proposed approaches rely on static RGB frames and on neutral facial expressions. This has two disadvantages. First, important facial shape cues are ignored. Second, facial deformations due to expressions can have an impact on the performance of such a method. In this paper, we propose a novel framework for dynamic 3D face identification/recognition based on facial keypoints. Each dynamic sequence of facial expressions is represented as a spatio-temporal graph, which is constructed using 3D facial landmarks. Each graph node contains local shape and texture features that are extracted from its neighborhood. For the classification/identification of faces, a Spatio-temporal Graph Convolutional Network (ST-GCN) is used. Finally, we evaluate our approach on a challenging dynamic 3D facial expression dataset.
