ProPose Dataset

This repository hosts the dataset for ProPose: Topology-Unified 2D Pose Estimation across Intact, Residual and Prosthetic Limbs.

ProPose is a 2D human pose estimation benchmark designed for inclusive pose estimation across intact, residual, and prosthetic limbs. It follows the proposed Omni-Pose annotation protocol, which represents biological, prosthetic, and physically absent keypoints within a unified topology.

Dataset File

The dataset is released as a single ZIP archive:

ProPose.zip

After downloading and extracting the archive, the dataset is organized into training, validation, and test splits.

Dataset Structure

ProPose.zip contains the following structure:

ProPose/
├── train/
│   ├── images/
│   └── propose_train.json
├── val/
│   ├── images/
│   └── propose_val.json
└── test/
    ├── images/
    └── propose_test.json

Each split contains:

• images/: image files used for training, validation, or testing.
• propose_*.json: the corresponding pose annotation file following the Omni-Pose annotation format.

Annotation Format

The annotation files include 2D keypoint coordinates and semantic keypoint type labels. Each keypoint is associated with a semantic type:

• Bio: biological keypoint.
• Pros: prosthetic keypoint.
• Abs: physically absent keypoint.

This design enables unified pose representation for intact limbs, residual limbs, and prosthetic limbs.
