摘要:

仅从单目RGB图像对中捕获密集的3D面部运动对于从面部表情识别到面部再现的许多应用来说是一个极具挑战性的问题。在这项工作中,我们提出了DeepFaceFlow,这是一个强大,快速,高精度的框架,用于对单目图像之间的3D非刚性面部流进行密集估计。我们的DeepFaceFlow框架在两个非常大规模的面部视频数据集上进行了训练和测试,其中一个是我们自己的集合和注释,并借助基于遮挡感知和3D的损失函数。我们进行了全面的实验,探索我们的方法的不同方面,并证明其对最先进的流和3D重建方法的性能改善。此外,我们将我们的框架在一个完整的头部国家的最先进的面部视频合成方法,并证明我们的方法在更好地表示和捕捉面部动态的能力,从而在一个高度逼真的面部视频合成。给定注册的图像对,我们的框架以约60 fps的速度生成3D流图。

英文摘要:

Dense 3D facial motion capture from only monocular in-the-wild pairs of RGB images is a highly challenging problem with numerous applications, ranging from facial expression recognition to facial reenactment. In this work, we propose DeepFaceFlow, a robust, fast, and highly-accurate framework for the dense estimation of 3D non-rigid facial flow between pairs of monocular images. Our DeepFaceFlow framework was trained and tested on two very large-scale facial video datasets, one of them of our own collection and annotation, with the aid of occlusion-aware and 3D-based loss function. We conduct comprehensive experiments probing different aspects of our approach and demonstrating its improved performance against state-of-the-art flow and 3D reconstruction methods. Furthermore, we incorporate our framework in a full-head state-of-the-art facial video synthesis method and demonstrate the ability of our method in better representing and capturing the facial dynamics, resulting in a highly-realistic facial video synthesis. Given registered pairs of images, our framework generates 3D flow maps at ~60 fps.
