Abstract

We present a novel generative model that synthesizes photorealistic, biophysically plausible faces by capturing the intricate relationships between facial geometry and biophysical attributes. Our approach models facial appearance in a biophysically grounded manner, allowing for the editing of both high-level attributes such as age and gender, as well as low-level biophysical properties such as melanin level and blood content. This enables continuous modeling of physical skin properties that correlate changes in skin properties with shape changes. We showcase the capabilities of our framework beyond its role as a generative model through two practical applications: editing the texture maps of 3D faces that have already been captured, and serving as a strong prior for face reconstruction when combined with differentiable rendering. Our model allows for the creation of physically-based relightable, editable faces with consistent topology and uv layout that can be integrated into traditional computer graphics pipelines.

可控生物物理人脸
我们提出了一种新的生成模型,通过捕捉面部几何和生物物理属性之间的复杂关系,合成逼真的、生物物理上可信的面部。我们的方法以生物物理为基础的方式建模面部外观,允许编辑高级属性,如年龄和性别,以及低级生物物理属性,如黑色素水平和血液含量。这使物理皮肤属性能够连续建模,使皮肤属性的变化与形状变化相关联。我们通过两个实际应用展示了我们的框架的功能,超出了它作为生成模型的作用:编辑已经捕获的3D人脸的纹理图,并在与可微分渲染相结合时作为人脸重建的强大先验。我们的模型允许创建基于物理的可照明、可编辑的面,具有一致的拓扑和uv布局,可以集成到传统的计算机图形管道中。
