PCDMs

Implementation code：Advancing Pose-Guided Image Synthesis with Progressive Conditional Diffusion Models, accepted at International Conference on Learning Representations (ICLR) 2024.

[Note!!!]: We have released a simplified version of PCDMs, using only stage 2, and trained with data from TikTok and DeepFashion to test the model's generalization capability. However, due to limited computational power and data, the results are not very stable. Therefore, this is an experimental version. The weights can be obtained from Google drive.

Generated Results (Paper)

You can directly download our test results from Google Drive: (1) PCDMs vs SOTA (2) PCDMs Results.

The PCDMs vs SOTA compares our method with several state-of-the-art methods e.g. ADGAN, PISE, GFLA, DPTN, CASD, NTED, PIDM. Each row contains target_pose, source_image, ground_truth, ADGAN, PISE, GFLA, DPTN, CASD, NTED, PIDM, and PCDMs (ours) respectively.

Third-party Usage: ComfyUI_PCDMs

Installation

Download dwpose weights (dw-ll_ucoco_384.pth, yolox_l_8x8_300e_coco_20211126_140236-d3bd2b23.pth) following this.

# install diffusers & pose extractor
pip install diffusers==0.24.0
pip install controlnet-aux==0.0.7
pip install transformers==4.32.1
pip install accelerate==0.24.1

# install DWPose which is dependent on MMDetection, MMCV and MMPose
pip install -U openmim
mim install mmengine
mim install "mmcv>=2.0.1"

Dataset

Processed Data

This link contains processed and prepared data that is ready for use. The data has been processed in the following ways:

• Rename image

• Split the train/test set

• keypoints extracted with Openpose

The folder structure of dataset should be as follows:
