Reproducing results in the paper

We provide two scripts to help reproduce the results shown in the paper.

After installing the environment and the dataset, for evaluation on the ZJU-MoCap dataset, run:

sh scripts/eval_zjumocap.sh

For evaluation on the MonoCap dataset, run:

sh scripts/eval_monocap.sh

Evaluation on ZJU-MoCap

Let’s take “377” as an example.

Training on ZJU-MoCap can be done by running.

export name=377
python train_net.py --cfg_file configs/inb/inb_${name}.yaml exp_name inb_${name} gpus ${GPUS} 

Evaluation can be done by running:

export name=377
python run.py --type evaluate --cfg_file configs/inb/inb_${name}.yaml exp_name inb_${name} gpus ${GPUS}

Evaluation on MonoCap

Let’s take “lan” as an example.

Training on Monocap can be done by running:

export name=lan
python train_net.py --cfg_file configs/inb/inb_${name}.yaml exp_name inb_${name} gpus ${GPUS} 

Evaluation can be done by running:

export name=lan
python run.py --type evaluate --cfg_file configs/inb/inb_${name}.yaml exp_name inb_${name} gpus ${GPUS}

TODO List

This repository currently serves as the release of the technical paper’s implementation and will undergo future updates (planned below) to enhance user-friendliness. We warmly welcome and appreciate any contributions.

• Instruction on running on custom datasets (Kudos to @tian42chen!!)
• Add support for further acceleration using CUDA
• Add a Google Colab notebook demo
