A Unified Framework for Domain Adaptive Pose Estimation, ECCV 2022

Code for A Unified Framework for Domain Adaptive Pose Estimation, ECCV 2022

Donghyun Kim*, Kaihong Wang*, Kate Saenko, Margrit Betke, and Stan Sclaroff.

Introduction

While several domain adaptive pose estimation models have been proposed recently, they are not generic but only focus on either human pose or animal pose estimation, and thus their effectiveness is somewhat limited to specific scenarios. In this work, we propose a unified framework that generalizes well on various domain adaptive pose estimation problems.

Method

We propose a unified freamwork for domain adaptive pose estimation on various objects including human body, human hand and animal that requires a (synthetic) labeled source domain dataset and a (real-world) target domain dataset without annotations. The system consists of a style trasnfer module to mitigate visual domain gap and a mean-teacher framework to encourage feature-level unsupervised learning from unlabeled images. For further details regarding our method, please refer to our paper.

Usage

Our code is based on the implmentation of RegDA, UDA-Aniaml.

Data Preparation

Human Dataset

As instructed by RegDA, following datasets can be downloaded automatically:

• Rendered Handpose Dataset
• Hand-3d-Studio Dataset
• FreiHAND Dataset
• Surreal Dataset
• LSP Dataset

You need to prepare following datasets manually if you want to use them:

• Human3.6M Dataset

Aniaml Dataset

Following UDA-Animal-Pose and CCSSL:

• Create a ./animal_data directory.
• Download the synthetic dataset by running bash get_dataset.sh.
• Download the TigDog dataset and move folder behaviorDiscovery2.0 to ./animal_data/.
• Download a cleaned annotation file of the synthetic dataset for better time performance from here and place the folder clean_data under ./animal_data/.

Pretrained Models

Before training, please make sure style transfer models are downloaded and saved in the "saved_models" folder under this directory. Pretrained style transfer models in all experiments are available here.

To pretrain a style transfer model on your own:

1. Go to ./adain/ directory.
2. For pretraining on human datasets (e.g. SURREAL->Human36M), run

python train/train_human.py --source SURREAL --target Human36M_mt --source_root path/to/SURREAL  --target_root path/to/Human36M --exp_name s2h_0_1 --style_weight 0.1

3. For pretraining on animal datasets (e.g. SyntheticAniaml->TigDog), run

python train/train_animal.py --image-path ../animal_data  --source synthetic_animal_sp_all --target real_animal_all --target_ssl real_animal_all_mt --train_on_all_cat --exp_name syn2td_0_1 --style_weight 0.1
