Explicit Box Detection Unifies End-to-End Multi-Person Pose Estimation

This is the official pytorch implementation of our ICLR 2023 paper "Explicit Box Detection Unifies End-to-End Multi-Person Pose Estimation ".

⭐ ED-Pose

We present ED-Pose, an end-to-end framework with Explicit box Detection for multi-person Pose estimation. ED-Pose re-considers this task as two explicit box detection processes with a unified representation and regression supervision. In general, ED-Pose is conceptually simple without post-processing and dense heatmap supervision.

1. For the first time, ED-Pose, as a fully end-to-end framework with a L1 regression loss, surpasses heatmap-based Top-down methods under the same backbone by 1.2 AP on COCO.
2. ED-Pose achieves the state-of-the-art with 76.6 AP on CrowdPose without test-time augmentation.

🔥 News

• 2023/08/08: 1. We support ED-Pose on the Human-Art dataset. 2. We upload the inference script for faster virtualization.

🐟 Todo

This repo contains further modifications including:

• Integrated into detrex.

• Integrated into Huggingface Spaces 🤗 using Gradio.

🚀 Model Zoo

We have put our model checkpoints here.

Note:

• Any test-time augmentations is not used for ED-Pose.
• We use the Object365 dataset to pretrain the human detection of ED-Pose under the Swin-L-5scale setting.

🚢 Environment Setup

Installation

We use the DN-Deformable-DETR as our codebase. We test our models under python=3.7.3,pytorch=1.9.0,cuda=11.1. Other versions might be available as well.

1. Clone this repo

git clone https://github.com/IDEA-Research/ED-Pose.git
cd ED-Pose

2. Install Pytorch and torchvision

Follow the instruction on https://pytorch.org/get-started/locally/.

# an example:
conda install -c pytorch pytorch torchvision

3. Install other needed packages

pip install -r requirements.txt

4. Compiling CUDA operators

cd models/edpose/ops
python setup.py build install
# unit test (should see all checking is True)
python test.py
cd ../../..
