• Tested with python3.7 on Ubuntu 16.04, CUDA 10.2.

• pytorch (tested on 1.10.0+cu102)

• torchvision (tested on 0.11.0+cu102)

• pytorch3d (tested on 0.6.1)

• numpy

• OpenCV

• tqdm

• yacs >= 0.1.8

• Download necessary assets (including the pre-trained models) from misc.tar.gz and unzip it.
• Register and download MANO data. Put MANO_LEFT.pkl and MANO_RIGHT.pkl in misc/mano

After collecting the above necessary files, the directory structure of ./misc is expected as follows:

./misc
├── mano
│   └── MANO_LEFT.pkl
│   └── MANO_RIGHT.pkl
├── model
│   └── config.yaml
│   └── interhand.pth
│   └── wild_demo.pth
├── graph_left.pkl
├── graph_right.pkl
├── upsample.pkl
├── v_color.pkl

1. Real-time demo :

python apps/demo.py --live_demo

2. Single-image reconstruction :

python apps/demo.py --img_path demo/ --save_path demo/

Results will be stored in folder ./demo

Noted: We don't operate hand detection, so hands are expected to be roughly at the center of image and take approximately 70-90% of the image area.

1. Download InterHand2.6M dataset and unzip it. (Noted: we used the v1.0_5fps version and H+M subset for training and evaluating)

2. Process the dataset by :

python dataset/interhand.py --data_path PATH_OF_INTERHAND2.6M --save_path ./interhand2.6m/

Replace PATH_OF_INTERHAND2.6M with your own store path of InterHand2.6M dataset.

3. Run evaluation:

python apps/eval_interhand.py --data_path ./interhand2.6m/

You would get following output :

joint mean error:
    left: 8.93425289541483 mm, right: 8.663229644298553 mm
    all: 8.798741269856691 mm
vert mean error:
    left: 9.173248894512653 mm, right: 8.890160359442234 mm
    all: 9.031704626977444 mm

The pytorch implementation of MANO is based on manopth. The GCN network is based on hand-graph-cnn. The heatmap generation and inference is based on DarkPose. We thank the authors for their great job!
