Holistically-Attracted Wireframe Parsing: From Supervised Learning to Self-Supervised Learning

This is the official implementation of our paper.

[News] Our journal version has been accepted in PAMI!

[News] The upgraded HAWPv2 and HAWPv3 are available now!

Highlights

  • HAT Fields: A General and Robust Representation of Line Segments for Wireframe Parsing
  • HAWPv2: A state-of-the-art fully-supervised wireframe parser. Please checkout HAWPv2.md for its details.
  • HAWPv3: A state-of-the-art self-supervised wireframe parser. Please checkout HAWPv3.md for its details and HAWPv3.train.md for the training recipe.
  • HAWPv3 can be used as a good wireframe parser for the out-of-distribution images.

  • We provide a running example on the images of DTU dataset (scene24) as below. 
    python -m hawp.ssl.predict --ckpt checkpoints/hawpv3-imagenet-03a84.pth  \
  --threshold 0.05  \
  --img ~/datasets/DTU/scan24/image/*.png \ 
  --saveto docs/figures/dtu-24 --ext png \

Data Downloading

Training and Testing datasets for HAWPv2

  • The training and testing data (including Wireframe dataset and YorkUrban dataset) for HAWPv2 can be downloaded via Google Drive. Many thanks to authors of these two excellent datasets!

  • You can also use the gdown to download the data in the terminal by

    gdown 134L-u9pgGtnzw0auPv8ykHqMjjZ2claO
unzip data.zip

Installation

Anaconda
  • Clone the code repo: git clone https://github.com/cherubicXN/hawp.git.
  • Install ninja-build by sudo apt install ninja-build.
  • Create a conda environment by
conda create -n hawp python==3.9
conda activate hawp
pip install -e .
  • Run the following command lines to install the dependencies of HAWP
# Install pytorch, please be careful for the version of CUDA on your machine
pip install torch==1.12.0+cu116 torchvision==0.13.0+cu116 torchaudio==0.12.0 --extra-index-url https://download.pytorch.org/whl/cu116 
# Install other dependencies
pip install -r requirement.txt
  • Verify the installation.
python -c "import torch; print(torch.cuda.is_available())" # Check if the installed pytorch supports CUDA.
  • Downloading the offically-trained checkpoints of both HAWPv2 and HAWPv3.
sh downloads.sh
Docker

We also provide a Dockerfile. You could build the docker image by running the following command lines.

sudo docker build - < Dockerfile --tag hawp:latest
