Deep Depth from Focal Stack with Defocus Model for Camera Setting Invariance

teaser This is the official pytorch implementation of "Deep Depth from Focal Stack with Defocus Model for Camera-Setting Invariance," IJCV.

Paper | arXiv

Requirements

CUDA 11.1
pytorch 1.8.0
tqdm
matplotlib
scikit-image
h5py

Download trained models

Our trained model can be downloaded here.

tar -zxvf checkpoint.tar.gz

Test on Mobile Depth

cd dataset/MobileDepth/data

Download the original data from https://www.supasorn.com/dffdownload.html:

wget https://www.supasorn.com/data/depth_from_focus_data2.zip
wget https://www.supasorn.com/data/depth_from_focus_data3.zip
unzip https://www.supasorn.com/data/depth_from_focus_data2.zip
unzip https://www.supasorn.com/data/depth_from_focus_data3.zip

Download depth maps:

tar -zxvf mobile_depth.tar.gz

Compute cost volumes:

cd ../python
python compute_cost_volume.py test

To get results, please run the following at DDFS/

python test.py checkpoint --dataset MOBILDE_DEPTH

Test on NYU Depth V2

cd dataset/NYUDepthV2

Download the original dataset:

wget http://horatio.cs.nyu.edu/mit/silberman/nyu_depth_v2/nyu_depth_v2_labeled.mat

Download focal stacks here (the script to synthesize them is in https://github.com/marcelampc/d3net_depth_estimation)

tar -zxvf focal_stack.tar.gz

Compute cost volumes:

python compute_cost_volume.py test test_index.txt

To get results, please run the following at DDFS/

python test.py checkpoint --dataset NYU_DEPTH_V2

Test on real focal stack

cd dataset/NikonD5300

Our focal stacks captured with Nikon D5300 can be downloaded here.

tar -zxvf nikon_focal_stack.tar.gz

Compute cost volumes:

python compute_cost_volume.py test

To get results, please run the following at DDFS/

python test.py --dataset NIKON_D5300

Run baseline method

We also provided the trained model of DefocusNet as a baseline method. At first, please download the original code as follows:

git clone https://github.com/dvl-tum/defocus-net.git

Then run the following

python test.py --method DEFOCUS_NET --dataset MOBILE_DEPTH | NYU_DEPTH_V2
