DwNet

This is the code repository complementing the paper "DwNet: Dense warp-based network for pose-guided human video generation". The pretrained models are included in the repo.

Dependencies and Setup

  • Python 2.7.12
  • DensePose
  • numpy==1.15.0
  • dominate==2.3.4
  • torch==1.0.1.post2
  • scipy==1.1.0
  • matplotlib==2.2.3
  • torchvision==0.2.1
  • tensorflow_gpu==1.11.0
  • Pillow==7.2.0
  • tensorflow==2.2.0

Experiments

Datasets

All data in this project relies on the DensePose[1] output. For the source image and the driving video you would need to extract the DensePose estimation, which are essentially human pixels of an RGB image mapped to the 3D surface of the human body. You can find examples of this preproccessed data in the datasets/ folder for Fashion and Tai-Chi datasets. Any video has to be saved as a separate folder of .PNG images (see the datasets/).

To install the DensePose I used their docker version described at the bottom here.

Fashion dataset

Videos for train and test can be downloaded from here.

Tai-Chi dataset

To obtain this dataset please refer to the original source[2].

Test

python test.py --name taichi_best  --dataroot datasets/taichi_test/  --gpu_ids 0

To test the transfer between different videos:

python test.py --name taichi_best  --dataroot datasets/taichi_test/  --gpu_ids 0 --transfer --transfer_file ./datasets/taichi_pairs.csv

--transfer_file points to a file with pairs of folders, where the first folder is a source for the frame to be transferred onto the driving video from the second column. Since we have just two examples in the test datasets, we only have two rows of pairs.

Train

To train from scratch you should use this command:

python train.py --name testing_taichi  --dataroot ../path/to/the/train/dataset --batchSize 8 --gpu_ids 0

If you want to load a pretrained model then please use a flag --load_pretrained:

python train.py --name testing_taichi  --dataroot ../path/to/the/train/dataset --batchSize 8 --gpu_ids 0 --load_pretrain checkpoints/taichi_best/

This would load the model that is included in the repo.

Acknowledgements

This implementation adapts a lot of code from the Pix2PixHD[3].
