摘要:

当前的面部动画方法虽然能够单独操控表情,但仍存在若干局限。一些基于运动的面部重现模型所操控的表情较为粗糙;而基于面部动作单元建模的思路则无法泛化到标注未涵盖的任意表情。本文提出一种新颖的几何感知面部表情迁移(GaFET)框架,该框架基于参数化三维面部表示,能够稳定地解耦表情。其中,我们提出了一个多层级特征对齐Transformer,用于补充非几何的面部细节特征,同时解决空间特征的对齐难题。此外,我们设计了一个基于StyleGAN的去表情模型,以降低GaFET在不成对的“自然场景”图像上的学习难度。大量定性和定量实验表明,与最先进方法相比,我们实现了更高质量、更准确的面部表情迁移结果,并展示了对多种姿态和复杂纹理的适用性。此外,本方法无需视频或标注训练数据,因而更易于使用和泛化。

英文摘要:

While current face animation methods can manipulate expressions individually, they suffer from several limitations. The expressions manipulated by some motion-based facial reenactment models are crude. Other ideas modeled with facial action units cannot generalize to arbitrary expressions not covered by annotations. In this paper, we introduce a novel Geometry-aware Facial Expression Translation (GaFET) framework, which is based on parametric 3D facial representations and can stably decoupled expression. Among them, a Multi-level Feature Aligned Transformer is proposed to complement non-geometric facial detail features while addressing the alignment challenge of spatial features. Further, we design a De-expression model based on StyleGAN, in order to reduce the learning difficulty of GaFET in unpaired "in-the-wild" images. Extensive qualitative and quantitative experiments demonstrate that we achieve higher-quality and more accurate facial expression transfer results compared to state-of-the-art methods, and demonstrate applicability of various poses and complex textures. Besides, videos or annotated training data are omitted, making our method easier to use and generalize.
