Description
MosquitoNR is a noise reduction filter designed for mosquito noise, which is often caused by lossy compression such as MPEG.
This filter works as follows:
- 1. Compute low frequency components of the image.
- 2. Apply direction-aware blur (smoothing). This blur effectively reduces compression artifacts, but also breaks detail.
- 3. Restore the low frequency components to the blurred image.
MosquitoNR processes luma only, to correctly process chroma take a look at the example below.
Requirements
- [x86] AviSynth+ or AviSynth 2.6.0
- [x64] AviSynth+
- Progressive input only
- Supported color formats: YUY2, YV12, YV16, YV24, YV411, Y8
- CPU with SSE2 support
Syntax and Parameters
- MosquitoNR (clip, int "strength", int "restore", int "radius", int "threads")
- clip =
- Input clip
- clip =
- int strength = 16
- Range: 0 - 32
- Sets the strength of the blur.
- Setting this value higher brings stronger noise reduction effect, but side effect will also become stronger.
- Range: 0 - 32
- int strength = 16
- int restore = 128
- Range: 0 - 128
- Sets the rate of restoring.
- If set to 0, no restoring is performed.
- If set to 128, low frequency components of the blurred image is completely replaced with those of the original image, and runs slightly faster.
- Range: 0 - 128
- int restore = 128
- int radius = 2
- Range: 1 - 2
- Sets the radius of the blur.
- 1 is faster, but will have insufficient effect in some cases.
- Range: 1 - 2
- int radius = 2
- int threads = 0
- Range: 0 - 32
- Controls how many threads are used.
- By default, threads is set equal to automatically detected number of processors.
- Since this filter needs a lot of memory access, thread efficiency is not very good. Setting this value lower might improve overall processing speed.
- Range: 0 - 32
- int threads = 0
Examples
MosquitoNR with default settings:
AviSource("Blah.avi") MosquitoNR(strength=16, restore=128, radius=2, threads=0)
MosquitoNR processes only luma.
If you want to process chroma too, you can write a script like the following, but there might be no noticeable change.
AviSource("Blah.avi") MosquitoNR() u = UtoY8().MosquitoNR() v = VtoY8().MosquitoNR() YtoUV(u, v, last)

This filter is a combination of flash3kyuu's AviUtl plugin "smoothing filter" and nilpo's AviUtl plugin "low frequency components protection filter".
This combination was proposed by POP@4bit. I thank all of them very much.
