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

  1. Equidistributed - noise with even distribution
  2. Normaldistributed - noise with normal distribution
  3. Color stains - color stains with normal distribution
  4. Echo signal - as TV echoed signal

Noise parameters
  1. Y strength - Y channel noise strength
  2. Cr strength - Cr channel noise strength
  3. Cb strength - Cb channel noise strength
  4. Stain size - size of stains (for Color stains noise type only)
  5. 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
Source frame
Equidistributed noise
Equidistributed: MSUNoiseGenerator(0, 15, 15, 15)		 Normaldistributed noise
Normaldistributed: MSUNoiseGenerator(1, 15, 15, 15)
Color stains
Color stains: MSUNoiseGenerator(2, 15, 15, 15,16)		 Echo signal
Echo signal: MSUNoiseGenerator(3, 25, 0, 0, 32)

Another example is frame No. 100 from bus sequence.

Public MSU video filters
Here are available VirtualDub and AviSynth filters. For a given type of digital video filtration we typically develop a family of different algorithms and implementations. Generally there are also versions optimized for PC and hardware implementations (ASIC/FPGA/DSP). These optimized versions can be licensed to companies. Please contact us for details via video(at)graphics.cs.msu_ru. 		Filters for companies
We are working with Intel, Samsung, RealNetworks and other companies on adapting our filters other video processing algorithms for specific video streams, applications and hardware like TV-sets, graphics cards, etc. Some of such projects are non-exclusive. Also we have internal researches. Please let us know via video(at)graphics.cs.msu_ru if you are interested in acquiring a license for such filters or making a custom R&D project on video processing, compression, computer vision.
