UV-IDM: Identity-Conditioned Latent Diffusion Model for Face UV-Texture Generation

Official implementation from UV-IDM (GitHub), presented at CVPR 2024.

Overview

UV-IDM generates photo-realistic facial UV textures based on the Basel Face Model (BFM). It leverages a latent diffusion model (LDM) for detailed texture generation and an identity-conditioned module to preserve identity consistency during 3D face reconstruction.

Key Features

Identity-Conditioned Generation: Uses any in-the-wild image as a robust condition to guide texture generation while maintaining identity
BFM-Compatible: Easily adaptable to different BFM-based 3D face reconstruction methods
High-Fidelity Output: Generates detailed facial textures within seconds
BFM-UV Dataset: Large-scale publicly available UV-texture dataset based on BFM

Checkpoint Structure

Place the downloaded checkpoint files in this directory with the following structure:

./
├── checkpoints/     # Model weights
├── pretrained/      # Pre-trained models
├── BFM/             # Basel Face Model files
└── third_party/     # Third-party dependencies

Download the checkpoint files from the official link (see README for the Google Drive link).

Usage

Inference

Create a filelist containing absolute paths to your input images, then run:

bash

# Quick start with example images
CUDA_VISIBLE_DEVICES=0 python scripts/visualize.py --images_list_file test.txt --outdir test_imgs/output

# With your own images
CUDA_VISIBLE_DEVICES=0 python scripts/visualize.py --images_list_file your_txt_list --outdir your_output_path

The network outputs: render image, UV map, and OBJ file.
