Hierarchical Temporal Transformer for 3D Hand Pose Estimation and Action Recognition from Egocentric RGB Videos
Original implementation of the paper Yilin Wen, Hao Pan, Lei Yang, Jia Pan, Taku Komura and Wenping Wang, "Hierarchical Temporal Transformer for 3D Hand Pose Estimation and Action Recognition from Egocentric RGB Videos", CVPR, 2023. [Paper][Supplementary Video]
A version of extended abstract was accpeted by the Human Body, Hands, and Activities from Egocentric and Multi-view Cameras Workshop, ECCV, 2022. [Extended Abstract]
The code is tested with the following environment:
Ubuntu 20.04
python 3.9
pytorch 1.10.0
torchvision 0.11.0
Other dependent packages as included in requirements.txt can be installed by pip. Note that we also refer to the utility functions in libyana. To install this libyana library, we follow LPC, CVPR 2020 to run:
pip install git+https://github.com/hassony2/[email protected]
To facilitate computation, for downloaded FPHA and H2O datasets: We resize all images into the 480x270 pixels, and use lmdb to manage the training images. One may refer to the preprocess_utils.py for related functions.
Our pretrained weights for FPHA and H2O, and other related data for running the demo code of the inference stage can be downloaded via the following link: [Inference Data] (included in the ws.zip)
which includes:
./ckpts/: The pretrained ckpt files for the FPHA and H2O datasets../curves/: .npz files for visualizing the 3D PCK(-RA) at different error thresholds on FPHA and H2O.
You may keep the downloaded ws folder under the root directory of this git repository.
Run
python plot_pck_curves.py
to plot the curves the 3D PCK(-RA) at different error thresholds on FPHA and H2O.
Run
CUDA_VISIBLE_DEVICES=0 python eval.py --batch_size <batch_size> \
--val_split <val_split> --train_dataset <dataset> --val_dataset <dataset> \
--dataset_folder <path_to_dataset_root> \
--resume_path <path_to_pth>
for evaluation on the dataset and split given by <dataset> and <val_split>.
Note that for the test split of H2O, we report the hand MEPE and action recall rate by referring to our submitted results in the H2O challenge codalab.
Run python train.py with parsed arguments to train a network with regard to your training data.
For the transformer architecture, we rely on the code of DETR, ECCV 2020 and Attention is All You Need, NeurIPS 2017.
For evaluation of 3D hand pose estimation, we follow the code of libyana and original ColorHandPose3DNetwork, ICCV 2017.
For data processing and augmentation, resnet architecture, and other utility functions, our code is heavily relied on the code of LPC, CVPR 2020 and libyana.
