DIP-denosing

This is a code repo for Rethinking Deep Image Prior for Denoising (ICCV 2021).

Addressing the relationship between Deep image prior and effective degrees of freedom, DIP-SURE with STE(stochestic temporal ensemble) shows reasonable result on single image denoising.

Working environment

• TITAN Xp
• ubuntu 18.04.4
• pytorch 1.6

Note: Experimental results were not checked in other environments.

Set-up

• Make your own environment

conda create --name DIP --file requirements.txt
conda avtivate DIP
pip install tqdm

Inference

• Produce CSet9 result

bash exp_denoising.sh CSet9 <GPU ID>

• For your own data with sigma=25 setup

mkdir testset/<YOUR_DATASET>
python main.py --dip_type eSURE_new --net_type s2s --exp_tag <EXP_NAME> --optim RAdam --force_steplr --desc sigma25   denoising --sigma 25 --eval_data <YOUR_DATASET>

Browsing experimental result

• We provide reporting code with invoke.

invoke showtable csv/<exp_type>/<exp_tag> 

• Example.

SSIM score

For SSIM score of color images, I used matlab code same as the author of S2S.
This is the demo code I received from the S2S author.
Thank you Mingqin!

% examples
ref = im2double(imread('gt.png'));
noisy = im2double(imread('noisy.png'));
psnr_result = psnr(ref, noisy);
ssim_result = ssim(ref, noisy);
