Abstract

Reconstruction of face 3D shape and its texture is a challenging task in the modern anthropology. While a skilled anthropologist could reconstruct an appearance of a prehistoric human from its skull, there are no automated methods to date for automatic anthropological face 3D reconstruction and texturing. We propose a deep learning framework for synthesis and visualization of photorealistic textures for 3D face reconstruction of prehistoric human. Our framework leverages a joint face-skull model based on generative adversarial networks. Specifically, we train two image-to-image translation models to separate 3D face reconstruction and texturing. The first model translates an input depth map of a human skull to a possible depth map of its face and its semantic parts labeling. The second model, performs a multimodal translation of the generated semantic labeling to multiple photorealistic textures. We generate a dataset consisting of 3D models of human faces and skulls to train our 3D reconstruction model. The dataset includes paired samples obtained from computed tomography and unpaired samples representing 3D models of skulls of prehistoric human. We train our texture synthesis model on the CelebAMask-HQ dataset. We evaluate our model qualitatively and quantitatively to demonstrate that it provides robust 3D face reconstruction of prehistoric human with multimodal photorealistic texturing.
