1 月 26 日消息,伦敦帝国理工学院和初创公司 FaceSoft.io 的研究人员设计出一个人脸建模系统 AvatarMe。AvatarMe 可以依据任意一张人脸照片和一些面部细节,生成 4K x 6K 分辨率的 3D 人脸模型。
AvatarMe 是首个能根据单一图像生成较高分辨率 3D 人脸模型的系统。在未来,AvatarMe 或可用于视频会议等各个 VR 应用场景。
这项研究发表于 CVPR 2020,论文标题为《AvatarMe:“在野外”的真实的可渲染的 3D 脸部重建(AvatarMe:Realistically Renderable 3D Facial Reconstruction “in-the-wild”)》。

CVPR(Conference on Computer Vision and Pattern Recognition)是由 IEEE 举办的计算机视觉和模式识别领域的顶级会议,本届会议在 6 月 13 日到 6 月 19 日之间举办。
AvatarMe:依据一张照片生成逼真的 3D 人脸
3D 人脸建模是计算机视觉、图形学、机器学习领域的研究焦点之一。在过去几年,许多研究团队研发了基于生成对抗性网络(GAN)的 3D 人脸建模系统。
GAN 由一个生成网络和一个判别网络组成。GAN 模型的学习过程就是生成网络和判别网络的相互博弈的过程:生成网络随机合成一张图片,让判别网络判断这张图片的真假,继而根据判别网络给出的反馈不断提高 “造假”能力,最终做到以假乱真。
但是,在依据任意人脸照片生成 3D 人脸模型方面,现有的解决方案普遍性能较差,生成的 3D 人脸模型分辨率较低。
训练过程中,研究人员首先输入一张低分辨率的人脸图片,用 3DMM 算法重建一个带纹理的基本几何体。然后,利用一个超级分辨率网络,研究人员重建纹理映射。接下来,研究人员利用一个去照明网络获得高分辨率的漫反射函数(AD)。最后,研究人员利用漫反射函数 AD 和基本几何体,推断出其他部分的函数(AS、ND、NS),进而建立仿真的 3D 人脸模型。
经过训练,AvatarMe 系统可以输出 4K x 6K 分辨率的 3D 人脸模型。
为了评估 AvatarMe 的性能,研究人员输入随机图片,观察 AvatarMe 重建的 3D 模型是否逼真。结果显示,AvatarMe 系统重建的 3D 人脸模型没有产生伪影。另外,在照片主人公戴有墨镜的情况下,系统也能较精准地建模。
结语:未来计划把 RealFaceDB 数据库开源
本项研究中,伦敦帝国理工学院和初创公司 FaceSoft.io 的研究人员设计出人脸建模系统 AvatarMe。AvatarMe 可以利用任意一张人脸照片,建立出较高分辨率的 3D 人脸模型。
