3D Hand Pose Estimation and 3D Hand Mesh Reconstruction

Compared with semi-automatic annotation methods in ICVL and MSRA datasets, our self-supervised method can generate more accurate and robust 3D hand pose and hand mesh.

      nyu-train-0-pose.txt
      ...

Pretrained Model

• Download our pre-trained model with self-supervised training [Google Drive]
• Download our pre-trained model with only synthetic data [Google Drive]
• Download the Consis-CycleGAN model [Google Drive]

Running DSF

Evaluation

Set load_model as the path to the pretrained model and change the phase to "test" in config.py, run

python train_render.py

Self-supervised Training

To perform self-supervised training, set finetune_dir as the path to the pretrained model with only synthetic data and tansferNet_pth as the path to the Consis-CycleGAN model in config.py. Then, change the phase to "train", run

python train_render.py

Pre-training with Synthetic Data

To perform pre-training, set train_stage to "pretrain" in config.py, run

python train_render.py
