More Demos on YouTube

Requirements

• Python 3.6+
• Pytorch tested on 0.4.1/1.0/1.2 versions
• PyTorch implementation of the Neural 3D Mesh Renderer for visualization

Installation

pip install -r requirements.txt

Demo

Simply go into DSD-SATN/src/, and run

sh run.sh

The results are saved in DSD-SATN/resources/results.

Re-implementation

1. Prepare model and data.

Step 1) Download the pre-trained models and statistical model from google drive. Unzip them under the project dir (e.g. DSD-SATN/trained_model, DSD-SATN/model)

Step 2) To download the processed annotations, please refer to the docs/dataset.md of ROMP. Unzip them and set their location in data_set_path of src/config.py like

data_set_path = {
    'h36m':'PATH/TO/H36M',
    ...
    'pw3d':'/PATH/TO/3DPW',}

About extracting frames from Human3.6M dataset that consist with the 3D annotation, please refer to src/dataset/extract_imgs_h36m.py.

Step 3) Apply for the datasets from official Human3.6M and 3DPW. Especially, pre-processing the input images of Human3.6M dataset. Extracting 1 frame from every 5 frame of video in Human3.6M dataset. Set the path of extracted images as {H36m_dir}/images and name each image as the format (Sn_action name_camera id_frame number.jpg) shown in h36m/h36m_test.txt (e.g. S11_Discussion 2_2_149.jpg).

2. Re-implement the evaluation results on Human3.6M and 3DPW datasets.

# Evaluating single-frame DSD network on 3DPW dataset

# Evaluating entire network (DSD-SATN) on 3DPW dataset
CUDA_VISIBLE_DEVICES=0 python3 test.py --gpu=0 --tab=video_3dpw --eval --eval-pw3d --video --eval-with-single-frame-network

Saving results & Visualization

Additionally, if you want to save the results, please add some options:

--save-obj # saving obj file of 3D human body mesh.
--save-smpl-params # saving smpl parameters.
--visual-all # saving all visual rendering results.

For example, saving all results of single-frame DSD network on Human3.6M dataset, just type

CUDA_VISIBLE_DEVICES=0 python3 test.py --gpu=0 --dataset=h36m --tab=single_h36m --eval --save-obj --save-smpl-params --visual-all

TODO List

• Releasing code for
  • testing
  • demo of single image
  • webcam demo
