Vague Denoiser is a wavelet based denoiser.

Basically, it transforms each frame from the video input into the wavelet domain, using Cohen-Daubechies-Feauveau 9/7. Then it applies some filtering to the obtained coefficients. It does an inverse wavelet transform after. Due to wavelet properties, it should give a nice smoothed result, and reduced noise, without blurring picture features.

It was originally written by Lefungus, and later modified by Kurosu and Fizick for further improvement. VapourSynth-VagueDenoiser was ported to VapourSynth interface and refactored by HolyWu. Kudos to them for creating and improving this fantastic tool.

This project backports VapourSynth-VagueDenoiser to AviSynth+. Parameter names follow VapourSynth-VagueDenoiser.

Usage

# AviSynth+
LoadPlugin("neo-vague-denoiser.dll")
neo_vd(clip, threshold=2.0, nsteps=6, y=3, u=3, v=3, ...)
# VapourSynth
core.neo_vd.VagueDenoiser(clip, threshold=2.0, nsteps=6, planes=[0,1,2], ...)

Parameters:

Check original VapourSynth-VagueDenoiser usage documents.

• y, u, v (AviSynth+ only)

  Whether a plane is to be filtered.

    1 - Do not touch, leaving garbage data
    2 - Copy from origin
    3 - Process
  

  Default: 3.

• opt

  Sets which CPU optimizations to use.

    0 - Auto detect
    1 - Use C
    2 - Use up to SSE (for core)
    3 - Use up to SSE4.1 (for data copy)
    4 - Use up to AVX (for core)
    5 - Use up to AVX2 (for data copy)
