TL;DR

If you want to cite and compare with out method, please download the generated images from Google Drive here. (Including 256x176, 512x352 on DeepFashion, and 128x64 on Market-1501)

News🔥🔥🔥

• 2024/02/27  Our paper titled "Coarse-to-Fine Latent Diffusion for Pose-Guided Person Image Synthesis" is accepted by CVPR 2024.
• 2024/02/28  We release the code and upload the arXiv preprint.
• 2024/03/09  The checkpoints on DeepFashion dataset is released on Google Drive.
• 2024/03/09  We note that the file naming used by different open source codes can be extremely confusing. To facilitate future work, we have organized the generated images of several methods that we used for qualitative comparisons in the paper. They were uniformly resized to 256X176 or 512x352, stored as png files and used the same naming format. Enjoy!🤗
• 2024/03/20  We upload the jupyter notebook for inference/reasoning. You could modify it as you want, e.g. replacing the conditional image with your customized one and randomly sampling a target pose from the test dataset.
• 2024/04/05  Our paper is accepted as CVPR 2024 Highlight!!!
• 2024/04/10  The camera-ready version is available on arXiv now. The supplementary material with more discussions and results was added.

Preparation

Install Environment

conda env create -f environment.yaml

Download DeepFashion Dataset

• Download Img/img_highres.zip from the In-shop Clothes Retrieval Benchmark of DeepFashion, unzip it under ./fashion directory. (Password would be required, please contact the authors of DeepFashion (not us!!!) for permission.)
• Download train/test pairs and keypoints from DPTN, put them under ./fashion directory.
• Make sure the tree of ./fashion directory is as follows.

  fashion
  ├── fashion-resize-annotation-test.csv
  ├── fashion-resize-annotation-train.csv
  ├── fashion-resize-pairs-test.csv
  ├── fashion-resize-pairs-train.csv
  ├── MEN
  ├── test.lst
  ├── train.lst
  └── WOMEN
  

• Run generate_fashion_datasets.py with python.

Download Pre-trained Models

• Download the following pre-trained models on demand, put them under ./pretrained_models directory.

  Model	Official Repository	Publicly Available
  U-Net	runwayml/stable-diffusion-v1-5	diffusion_pytorch_model.safetensors
  VAE	runwayml/stable-diffusion-v1-5	diffusion_pytorch_model.safetensors
  Swin-B	microsoft/Swin-Transformer	swin_base_patch4_window12_384_22kto1k.pth
  CLIP (ablation only)	openai/clip-vit-large-patch14	model.satetensors

• Make sure the tree of ./pretrained_models directory is as follows.
