Usage

Install dependencies

This code requires PyTorch 1.1.0 and python 3+. Please install dependencies by

pip install -r requirments.txt

Compile the DIB-Render

cd dib-render/cuda_dib_render
python build.py install

Inference

python test-all.py \
 --g_model_dir ./checkpoints/g_model.pth \
 --svfolder ./prediction \
 --data_folder ./dataset \
 --filelist ./test_list.txt

To get the evaluation IOU, please first download the tool Binvox and install it's dependencies,

Voxelize the prediction using Binvox

python voxelization.py  --folder ./prediction

To evaluate the IOU, please first install binvox-rw-py following this Link, then run the script

python check_iou.py --folder ./prediction  --gt_folder ./dataset

To get the boundary F-score, please run the following script

python check_chamfer.py --folder ./prediction  --gt_folder ./dataset
