ICCV 2021 (Oral)

Prerequisites

• Linux or macOS
• Python 3
• PyTorch 1.7+ and other dependencies (torchvision, visdom, dominate, and other common python libs)

Getting Started

• Clone this repository:

  git clone https://github.com/Huage001/PaintTransformer
  cd PaintTransformer

• Download pretrained model from Google Drive and move it to inference directory:

  mv [Download Directory]/model.pth inference/
  cd inference

• Inference:

  python inference.py

  • Input image path, output path, and etc can be set in the main function.
  • Notably, there is a flag serial as one parameter of the main function:
    • If serial is True, strokes would be rendered serially. The consumption of video memory will be low but it requires more time.
    • If serial is False, strokes would be rendered in parallel. The consumption of video memory will be high but it would be faster.
    • If animated results are required, serial must be True.

• Train:

  • Before training, start visdom server:

    python -m visdom.server

  • Then, simply run:

    cd train
    bash train.sh

  • You can monitor training status at http://localhost:8097/ and models would be saved at checkpoints/painter folder.

• You may feel free to try other training options written in train.sh.
