针对现有方法未考虑人脸语义信息且身份表示固定的问题,提出基于GAN的单样本渐进式人脸替换方法FaceSwapper,通过解耦表示模块和语义引导融合模块提升效果,在基准数据集上用更少样本取得最优结果。

摘要:

尽管人脸替换近年来备受关注,但它仍是一个具有挑战性的问题。现有方法利用大量数据样本探索人脸替换的内在属性,却未考虑人脸图像的语义信息。此外,身份信息的表示往往是固定的,导致人脸替换效果欠佳。在本文中,我们提出一种简单高效的方法FaceSwapper,它基于生成对抗网络(GAN)实现单样本人脸替换。我们的方法包含解耦表示模块和语义引导融合模块。解耦表示模块由属性编码器和身份编码器组成,旨在实现身份与属性信息的解耦。身份编码器更具灵活性,属性编码器比同类方法包含更多属性细节。得益于解耦表示,FaceSwapper可实现渐进式人脸替换。此外,语义引导融合模块引入语义信息,以控制替换区域并更准确地建模姿态与表情。实验结果表明,我们的方法在基准数据集上使用更少的训练样本取得了最先进的结果。我们的代码已公开于https://github.com/liqi-casia/FaceSwapper。

英文摘要:

Although face swapping has attracted much attention in recent years, it remains a challenging problem. Existing methods leverage a large number of data samples to explore the intrinsic properties of face swapping without considering the semantic information of face images. Moreover, the representation of the identity information tends to be fixed, leading to suboptimal face swapping. In this paper, we present a simple yet efficient method named FaceSwapper, for one-shot face swapping based on Generative Adversarial Networks. Our method consists of a disentangled representation module and a semantic-guided fusion module. The disentangled representation module comprises an attribute encoder and an identity encoder, which aims to achieve the disentanglement of the identity and attribute information. The identity encoder is more flexible, and the attribute encoder contains more attribute details than its competitors. Benefiting from the disentangled representation, FaceSwapper can swap face images progressively. In addition, semantic information is introduced into the semantic-guided fusion module to control the swapped region and model the pose and expression more accurately. Experimental results show that our method achieves state-of-the-art results on benchmark datasets with fewer training samples. Our code is publicly available at https://github.com/liqi-casia/FaceSwapper.
