# Neo Vague Denoiser (forked from VapourSynth-VagueDenoiser)
2+
3+
Neo Vague Denoiser Copyright(C) 2020 Xinyue Lu, and previous developers
4+
5+
Vague Denoiser is a wavelet based denoiser.
6+
7+
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.
8+
9+
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.
10+
11+
This project backports VapourSynth-VagueDenoiser to AviSynth+. Parameter names follow VapourSynth-VagueDenoiser.
12+
13+
## Usage
14+
15+
```python
16+
# AviSynth+
17+
LoadPlugin("neo-vague-denoiser.dll")
18+
neo_vd(clip, threshold=2.0, nsteps=6, y=3, u=3, v=3, ...)
19+
# VapourSynth
20+
core.neo_vd.VagueDenoiser(clip, threshold=2.0, nsteps=6, planes=[0,1,2], ...)
21+
```
22+
23+
Parameters:
24+
25+
[Check original VapourSynth-VagueDenoiser usage documents.](https://github.com/HomeOfVapourSynthEvolution/VapourSynth-VagueDenoiser/blob/master/README.md)
26+
27+
- *y*, *u*, *v* (AviSynth+ only)
28+
29+
Whether a plane is to be filtered.
30+
31+
1 - Do not touch, leaving garbage data
32+
2 - Copy from origin
33+
3 - Process
34+
35+
Default: 3.
