## Introduction
This repository is the official [Pytorch](https://pytorch.org/) implementation of [Beyond Static Features for Temporally Consistent 3D Human Pose and Shape from a Video](https://arxiv.org/abs/2011.08627). 
The base codes are largely borrowed from [VIBE](https://github.com/mkocabas/VIBE).
Find more qualitative results [here](https://youtu.be/WB3nTnSQDII).

## Installation
TCMR is tested on Ubuntu 16.04 with Pytorch 1.4 and Python 3.7.10. 
You may need sudo privilege for the installation.
```bash
source scripts/install_pip.sh
```

## Quick demo
- Download the pre-trained demo TCMR and required data by below command and download SMPL layers from [here](https://smpl.is.tue.mpg.de/en) (male&female) and [here](http://smplify.is.tue.mpg.de/) (neutral). Put SMPL layers (pkl files) under `${ROOT}/data/base_data/`.
```bash
source scripts/get_base_data.sh
```
- Run demo with options (e.g. render on plain background). See more option details in bottom lines of `demo.py`.
- A video overlayed with rendered meshes will be saved in `${ROOT}/output/demo_output/`. 
```bash
python demo.py --vid_file demo.mp4 --gpu 0 
```

## Results
Here I report the performance of TCMR.

See [our paper](https://arxiv.org/abs/2011.08627) for more details.

## Running TCMR

Download pre-processed data (except InstaVariety dataset) from [here](https://drive.google.com/drive/folders/1oG-vyE77jHUgdTu9tApJuMj8voJ7lklD?usp=sharing).
You may also download datasets from sources and pre-process yourself. Refer to [this](asset/data.md).
Put SMPL layers (pkl files) under `${ROOT}/data/base_data/`.

The data directory structure should follow the below hierarchy.
```
${ROOT}  
|-- data  
|   |-- base_data  
|   |-- preprocessed_data  
|   |-- pretrained_models
```

### Evaluation

- Download pre-trained TCMR weights from [here](https://drive.google.com/drive/folders/1a_nv8MfvToutatBvKaIXP7J_7U4BjSu2?usp=sharing).  
- Run the evaluation code with a corresponding config file to reproduce the performance in the tables of [our paper](https://arxiv.org/abs/2011.08627).
```bash
# dataset: 3dpw, mpii3d, h36m 
python evaluate.py --dataset 3dpw --cfg ./configs/repr_table4_3dpw_model.yaml --gpu 0 
```
- You may test options such as average filtering and rendering. See the bottom lines of `${ROOT}/lib/core/config.py`.
- We checked rendering results of TCMR on 3DPW validation and test sets.

### Reproduction (Training)

- Run the training code with a corresponding config file to reproduce the performance in the tables of [our paper](https://arxiv.org/abs/2011.08627).
```bash
# training outputs are saved in `experiments` directory
# mkdir experiments
python train.py --cfg ./configs/repr_table4_3dpw_model.yaml --gpu 0 
```
- Evaluate the trained TCMR (either `checkpoint.pth.tar` or `model_best.pth.tar`) on a target dataset.
- You may test the motion discriminator introduced in VIBE by uncommenting the codes that have `exclude motion discriminator` notations.
- We do not release [NeuralAnnot](https://arxiv.org/abs/2011.11232) SMPL annotations of [Human36M](http://vision.imar.ro/human3.6m/description.php) used in our paper yet. Thus the performance in Table 6 may be slightly different with the paper.
