ID-Patch: Build Identity-to-Position Association

To address ID leakage and the linear increase in generation time with the number of identities, we propose ID-Patch, a novel method for robust identity-to-position association. From the same facial features, we generate both an **ID patch**—placed on the conditional image for precise spatial control—and ID embeddings, which are fused with text embeddings to enhance identity resemblance.

Environment Setup

Note: Python 3.9 and CUDA 12.2 are required.

conda create -n idp python=3.9
conda activate idp
pip install -r requirements.txt

Download models from https://huggingface.co/ByteDance/ID-Patch, and put them under models/ folder.

git lfs install
git clone https://huggingface.co/ByteDance/ID-Patch

Demo

python demo.py

Argument	Description
--pose_image_path	Path to the pose image used for conditioning the generation. Default: data/poses/example_pose.png
--subject_dir	Directory containing subject identity images. Each image should represent one person. Default: data/subjects
--subjects	Comma-separated list of subject image filenames (e.g., exp_man.jpg,exp_woman.jpg). The order corresponds to their placement from left to right in the generated image.
--prompt	Text prompt describing the scene to be generated. This guides the overall content and style of the output image.
--base_model_path	Path to the base diffusion model to be used for generation. Default: RunDiffusion/Juggernaut-X-v10
--output_dir	Directory where the generated images will be saved. Default: results
--output_name	Filename prefix for the generated image(s). Default: exp_result

Disclaimer

Our released HuggingFace model differs from the paper’s version due to training on a different dataset.
