DVDnet

A state-of-the-art, simple and fast network for Deep Video Denoising

NEW: a state-of-the-art algorithm for video denoising without motion compensation FastDVDnet

Overview

This source code provides a PyTorch implementation of DVDnet image denoising, as in Tassano, Matias and Delon, Julie and Veit, Thomas. "DVDnet: A Fast Network for Deep Video Denoising", IEEE ICIP 2019, arXiv preprint arXiv:1906.11890 (2019).

Video examples

You can download several denoised sequences with our algorithm and other methods here

User Guide

The code as is runs in Python +3.6 with the following dependencies:

Dependencies

Usage

If you want to denoise an image sequence using the pretrained models found under the models folder you can execute

python test_dvdnet.py \
        --test_path <path_to_input_sequence> \
	--save_path results \
        --noise_sigma 25 \

NOTES

  • The image sequence should be stored under <path_to_input_sequence>
  • Models have 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
  • run with --help to see details on all input parameters

Comparison of PSNRs

Two different testsets were used for benchmarking our method: the DAVIS-test testset, and Set8, which is composed of 4 color sequences from the Derf’s Test Media collection and 4 color sequences captured with a GoPro camera. The DAVIS set contains 30 color sequences of resolution 854 x 480. The sequences of Set8 have been downscaled to a resolution of 960 x 540. In all cases, sequences were limited to a maximum of 85 frames. We used the DeepFlow algorithm to compute flow maps for DVDnet and VNLB. For Neat Video, the automatic noise profiling settings were used.

Note: values shown are the average for all sequences in the testset, the PNSR of a sequence is computed as the average of the PSNRs of each frame.
