This repository is the official implementation of Residual Denoising Diffusion Models.

Requirements

To install requirements:

conda env create -f install.yaml

Dataset

Raindrop (test-a for test)

GoPro

ISTD

SID-RGB: kexu or download

LOL

CelebA

Training

To train RDDM, run this command:

cd experiments/xxxx
python train.py

or

accelerate launch train.py

Evaluation

To evaluate image generation, run:

cd eval/image_generation_eval/
python fid_and_inception_score.py path_of_gen_img

For image restoration, MATLAB evaluation codes in ./eval.

Pre-trained Models

Two unets (deresidual+denoising) for partially path-independent generation process

Results

See Table 3 in main paper.

For image restoration:

Raindrop

GoPro

ISTD

LOL

SID-RGB

For image generation (on the CelebA dataset):

We can convert a pre-trained DDIM to RDDM by coefficient transformation (see 1_Image_Generation_convert_pretrained_DDIM_to_RDDM).
