Install

Prepare virtualenv using Poetry.

# Install required modules
poetry install --no-dev

# Enable Poetry's virtualenv
poetry shell

Dataset

Then, unzip the archive and store in the data folder. If the data is sanmiguel, four subdirectories (i.e., 32spp, 64spp, 128spp, and 4096spp) will be stored in data/sanmiguel.

Run

# To reproduce our results in the paper, run the following.
python main.py --data_root /path/to/data --spp 32 --ksize 13 --wlr simple --thres 1.00

The default parameters used to generate the following results are shown in run.sh. After running the above code, you can visually compare our method with other baselines with analysis.ipynb in the notebooks folder.

Results
