FastDVDnet

A state-of-the-art, simple and fast network for Deep Video Denoising which uses no motion compensation.

NEW: Paper to be presented at CVPR2020

Previous deep video denoising algorithm: DVDnet

Overview

This source code provides a PyTorch implementation of the FastDVDnet video denoising algorithm, as in Tassano, Matias and Delon, Julie and Veit, Thomas. "FastDVDnet: Towards Real-Time Deep Video Denoising Without Flow Estimation", arXiv preprint arXiv:1907.01361 (2019).

Video Examples

You can download several denoised sequences with our algorithm and other methods here (more videos coming soon)

Running Times

FastDVDnet is orders of magnitude faster than other state-of-the-art methods

Results

Left: Input noise sigma 40 denoised with FastDVDnet (sorry about the dithering due to gif compression)

Right: PSNRs on the DAVIS testset, Gaussian noise and clipped Gaussian noise

Architecture

Code User Guide

Dependencies

The code runs on Python +3.6. You can create a conda environment with all the dependecies by running (Thanks to Antoine Monod for the .yml file)

conda env create -f requirements.yml -n <env_name>

Note: this project needs the NVIDIA DALI package for training. The tested version of DALI is 0.10.0. If you prefer to install it yourself (supposing you have CUDA 10.0), you need to run

pip install --extra-index-url https://developer.download.nvidia.com/compute/redist/cuda/10.0 nvidia-dali==0.10.0

Testing

If you want to denoise an image sequence using the pretrained model you can execute

test_fastdvdnet.py \
	--test_path <path_to_input_sequence> \
	--noise_sigma 30 \
	--save_path results

NOTES

The image sequence should be stored under <path_to_input_sequence>
The model has been trained for values of noise in [5, 55]
run with --no_gpu to run on CPU instead of GPU
run with --save_noisy to save noisy frames
set max_num_fr_per_seq to set the max number of frames to load per sequence
to denoise clipped AWGN run with --model_file model_clipped_noise.pth
run with --help to see details on all input parameters

Training

If you want to train your own models you can execute

train_fastdvdnet.py \
	--trainset_dir <path_to_input_mp4s> \
	--valset_dir <path_to_val_sequences> \
	--log_dir logs
