摘要:

受到最近人脸图像编辑方法令人印象深刻的性能的启发,自然提出了一些研究来将这些方法扩展到人脸视频编辑任务。这里的主要挑战之一是编辑帧之间的时间一致性,这仍然是未解决的。为此,我们提出了一种新的人脸视频编辑框架的基础上扩散自动编码器,可以成功地提取分解的功能-第一次作为一个人脸视频编辑模型-从一个给定的视频的身份和运动。这种建模允许我们通过简单地将时间不变特征操纵到所需的方向来编辑视频,以实现一致性。我们模型的另一个独特优势是,由于我们的模型基于扩散模型,因此它可以同时满足重建和编辑功能,并且与现有的基于GAN的方法不同,它对野生人脸视频中的角点情况(例如,遮挡人脸)具有鲁棒性。

英文摘要:

Inspired by the impressive performance of recent face image editing methods, several studies have been naturally proposed to extend these methods to the face video editing task. One of the main challenges here is temporal consistency among edited frames, which is still unresolved. To this end, we propose a novel face video editing framework based on diffusion autoencoders that can successfully extract the decomposed features - for the first time as a face video editing model - of identity and motion from a given video. This modeling allows us to edit the video by simply manipulating the temporally invariant feature to the desired direction for the consistency. Another unique strength of our model is that, since our model is based on diffusion models, it can satisfy both reconstruction and edit capabilities at the same time, and is robust to corner cases in wild face videos (e.g. occluded faces) unlike the existing GAN-based methods.
