This repository contains the official code for the paper "UV-IDM: Identity-Conditioned Latent Diffusion Model for Face UV-Texture Generation", presented at CVPR 2024.

3D face reconstruction aims to generate high-fidelity 3D face shapes and textures from single-view or multi-view images. However, current prevailing facial texture generation methods generally suffer from low-quality texture, identity information loss, and inadequate handling of occlusions. To solve these problems, we introduce an Identity-Conditioned Latent Diffusion Model for face UV-texture generation (UV-IDM) to generate photo-realistic textures based on the Basel Face Model (BFM). UV-IDM leverages the powerful texture generation capacity of a latent diffusion model (LDM) to obtain detailed facial textures. To preserve the identity during the reconstruction procedure, we design an identity-conditioned module that can utilize any in-the-wild image as a robust condition for the LDM to guide texture generation. UV-IDM can be easily adapted to different BFM-based methods as a high-fidelity texture generator. Furthermore, in light of the limited accessibility of most existing UV-texture datasets, we build a large-scale and publicly available UV-texture dataset based on BFM, termed BFM-UV. Extensive experiments show that our UV-IDM can generate high-fidelity textures in 3D face reconstruction within seconds while maintaining image consistency, bringing new state-of-the-art performance in facial texture generation.

We recommend you to generate a filelist that contains the absolute path of your images. A possible demo is in test_imgs. Our network will generate three output, containing the render image, UV map and obj file.

You can start with our provided example by:

CUDA_VISIBLE_DEVICES=0 python scripts/visualize.py --images_list_file test.txt --outdir test_imgs/output

CUDA_VISIBLE_DEVICES=0 python scripts/visualize.py --images_list_file your_txt_list --outdir your_output_path
