Installation

Get the code:

git clone --recurse-submodules https://github.com/fkluger/parsac.git
cd parsac
git submodule update --init --recursive

Set up the Python environment using Anaconda:

conda env create -f environment.yml
source activate parsac

Datasets

HOPE-F

Download the HOPE-F dataset and extract it inside the datasets/hope directory. The small dataset w/o images is sufficient for training and evaluation.

Synthetic Metropolis Homographies

Download the SMH dataset and extract it inside the datasets/smh directory. The small dataset w/o images is sufficient for training and evaluation.

NYU-VP

The vanishing point labels and pre-extracted line segments for the NYU dataset are fetched automatically via the nyu_vp submodule.

YUD and YUD+

Pre-extracted line segments and VP labels are fetched automatically via the yud_plus submodule. RGB images and camera calibration parameters, however, are not included. Download the original York Urban Dataset from the Elder Laboratory's website and store it under the datasets/yud_plus/data subfolder.

Adelaide-H/-F

We provide a mirror of the Adelaide dataset here: https://cloud.tnt.uni-hannover.de/index.php/s/egE6y9KRMxcLg6T. Download it and place the .mat files inside the datasets/adelaide directory.

Evaluation

In order to reproduce the results from the paper using our pre-trained network, first download the neural network weights and then follow the instructions on the EVAL page.

Training

If you want to train PARSAC from scratch, please follow the instructions on the TRAIN page.
