FlashFace: Human Image Personalization with High-fidelity Identity Preservation

Project Page

Feature

1. Zero-shot human image customization within seconds with one or several reference faces.
2. Strong identity preservation ability, even for non-celebrities
3. Strong language prompts following ability, even changing the age or gender of the person.
4. Flexible strength adjustment for identity image control and language prompt control.

Updates

• [April 18] Inference code of FlashFace-SD1.5 are released.

This version represents a clear advancement over our paper, as it has been trained for an extended duration. We also involve new guidance techniques in the inference process. Notably, this enhanced checkpoint demonstrates remarkable progress in terms of lighting and shadow effects. It show strong identity preservation ability even for non-celebrities. Please refer to the following images for more details. For the prompt and inference parameters, please refer to notebook demo. If you are not satisfied with the generated images, you can submit your case in the issue so that we can help you improve it. Stay tuned for more versions!

我们开源了 FlashFace-SD1.5 的 inference 代码以及全微调的模型权重. 这个权重相比我们论文中权重训练了更长的时间，如下面图片，展现出了更真实的光影效果与人物细节,即使针对非名人它也展现出了极强的保 ID 能力. 下面图片使用的 prompt 以及 inference 参数细节 可以参照 notebook demo. 如果您对生成图片不满意，可以在 issue 中提交您的 case,以便我们帮助您提升它. 其他版本权重敬请期待！

You should download all the related weights and put them in the cache folder (e.g. FlashFace/cache/flashface.ckpt).

Demo

You can do the inference with the notebook demo or Gradio.

python flashface/all_finetune/demo_gradio.py

Acknowledgement

Inspired from many excellent demos and repos related to human image customization, including IP-Adapter, multimodalart/Ip-Adapter-FaceID, FastComposer, T2I-Adapter, PhotoMaker and InstantID. Thanks for their great work!
