VirtualDub MSU Noise Generation FilterMSU Graphics & Media Lab (Video Group)
Algorithm: Dr. Dmitriy Vatolin, 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' 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.

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) Òhird 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 anotherþ
