InterHand2.6M: A Dataset and Baseline for 3D Interacting Hand Pose Estimation from a Single RGB Image

Introduction

Above demo videos have low-quality frames because of the compression for the README upload.

News

  • 2020.10.7. Fitted MANO parameters are available!

InterHand2.6M dataset

  • For the InterHand2.6M dataset download and instructions, go to [HOMEPAGE].
  • Belows are instructions for our baseline model, InterNet, for 3D interacting hand pose estimation from a single RGB image.

MANO mesh rendering demo

  1. Install SMPLX
  2. cd MANO_render
  3. Set smplx_path and root_path in render.py
  4. Run python render.py

Directory

Root

The ${ROOT} is described as below.

${ROOT}
|-- data
|-- common
|-- main
|-- output
  • data contains data loading codes and soft links to images and annotations directories.
  • common contains kernel codes for 3D interacting hand pose estimation.
  • main contains high-level codes for training or testing the network.
  • output contains log, trained models, visualized outputs, and test result.

Data

You need to follow directory structure of the data as below.

${ROOT}
|-- data
|   |-- STB
|   |   |-- data
|   |   |-- rootnet_output
|   |   |   |-- rootnet_stb_output.json
|   |-- RHD
|   |   |-- data
|   |   |-- rootnet_output
|   |   |   |-- rootnet_rhd_output.json
|   |-- InterHand2.6M
|   |   |-- annotations
|   |   |   |-- all
|   |   |   |-- human_annot
|   |   |   |-- machine_annot
|   |   |-- images
|   |   |   |-- train
|   |   |   |-- val
|   |   |   |-- test
|   |   |-- rootnet_output
|   |   |   |-- rootnet_interhand2.6m_output_all_test.json
|   |   |   |-- rootnet_interhand2.6m_output_machine_annot_val.json

Output

You need to follow the directory structure of the output folder as below.

${ROOT}
|-- output
|   |-- log
|   |-- model_dump
|   |-- result
|   |-- vis
  • log folder contains training log file.
  • model_dump folder contains saved checkpoints for each epoch.
  • result folder contains final estimation files generated in the testing stage.
  • vis folder contains visualized results.

Running InterNet

Start

  • In the main/config.py, you can change settings of the model including dataset to use and which root joint translation vector to use (from gt or from RootNet).

Train

In the main folder, run

python train.py --gpu 0-3 --annot_subset $SUBSET

to train the network on the GPU 0,1,2,3. --gpu 0,1,2,3 can be used instead of --gpu 0-3. If you want to continue experiment, run use --continue.

$SUBSET is one of [all, human_annot, machine_annot].

  • all: Combination of the human and machine annotation. Train (H+M) in the paper.
  • human_annot: The human annotation. Train (H) in the paper.
  • machine_annot: The machine annotation. Train (M) in the paper.

Test

Place trained model at the output/model_dump/.

In the main folder, run

python test.py --gpu 0-3 --test_epoch 20 --test_set $DB_SPLIT --annot_subset $SUBSET

to test the network on the GPU 0,1,2,3 with snapshot_20.pth.tar. --gpu 0,1,2,3 can be used instead of --gpu 0-3.

$DB_SPLIT is one of [val,test].

  • val: The validation set. Val in the paper.
  • test: The test set. Test in the paper.

$SUBSET is one of [all, human_annot, machine_annot].

  • all: Combination of the human and machine annotation. (H+M) in the paper.
  • human_annot: The human annotation. (H) in the paper.
  • machine_annot: The machine annotation. (M) in the paper.

Results

Here I provide the performance and pre-trained snapshots of InterNet, and output of the RootNet as well.
