VirtualDub MSU Noise Generation Filter
- Algorithm: Dr. Dmitriy Vatolin, Konstantin Strelnikov
- Implementation: Konstantin Strelnikov
New version of filter!
The filter adds artificial noise of one common types (equidistributed, normally distributed, colour stains, echo signal) to video stream. It can be used for testing, debugging and comparison of various denoising filters.
Settings
‘Settings’ dialogue box allows to select type of noise to generation. Noise intensity can be specified for each colour component (the filter uses YCrCb colour space). Individual noise parameters also can be changed for some noise types.
Settings:
Noise type
- Equidistributed - noise with even distribution
- Normaldistributed - noise with normal distribution
- Color stains - color stains with normal distribution
- Echo signal - as TV echoed signal
Noise parameters
- Y strength - Y channel noise strength
- Cr strength - Cr channel noise strength
- Cb strength - Cb channel noise strength
- Stain size - size of stains (for Color stains noise type only)
- Echo delay - echoed signal delay (for Echo signal noise type only)

Job and AviSynth Script example for AviSynth:
LoadVirtualDubPlugin("...\Virtual Dub\plugins\MSU_NoiseGenerator.vdf","MSUNoiseGenerator", 0)
clip=AVISource("MSU.avi", false, "RGB24")
clip.ConvertToRGB32.MSUNoiseGenerator(2, 15, 5, 5,16)
First parameter - noise type: 0 - equidistributed; 1 -
normaldistributed; 2 - color stains; 3 - echo signal
Second parameter - Y channel noise strength (from 0 to 100 in case
Echo signal noise, from 0 to 255 another)
Тhird parameter - Cr channel noise strength (from 0 to 100 in case
Echo signal noise, from 0 to 255 another)
Fourth parameter - Cb channel noise strength (from 0 to 100 in case
Echo signal noise, from 0 to 255 another)
Fifth parameter - stain size in case Color stains noise (from 0 to
64); echo delay in case Echo signal noise (from 0 to 64); not used
anotherю
Examples
Next follow example of different noise types for frame 50 of foreman sequence.

Source frame

Equidistributed: MSUNoiseGenerator(0, 15, 15, 15)

Normaldistributed: MSUNoiseGenerator(1, 15, 15, 15)

Color stains: MSUNoiseGenerator(2, 15, 15, 15,16)

Echo signal: MSUNoiseGenerator(3, 25, 0, 0, 32)
Another example is frame No. 100 from bus sequence.

Source frame

Equidistributed: MSUNoiseGenerator(0, 20, 5, 5)

Normaldistributed: MSUNoiseGenerator(1, 0, 40, 40)

Color stains: MSUNoiseGenerator(2, 0 , 10, 20,32)

Echo signal: MSUNoiseGenerator(3, 30, 0, 0, 16)
