This filter is used to estimate mean noise variance in video sequences. The result is saved into a log file.


Settings


The basic menu of the filter

settings dialog box

Noise estimation algorithm - the algorithm used to estimate noise. Following modes supported:

  • MAD
  • Block-Based
  • Spatio-temporal gradients
  • All algorithms

Advanced - configure algorithm details

Write noise estimates for each frame into file - path to log file.

Configure algorithm details: Block-Based

block-based advanced dialog box

Block size - The parameter influencing on speed of work and accuracy of an estimation. The increase of this parameter reduces accuracy and reduces time of performance. For video with small homogeneous areas it is recommended to use smaller values.

Search step - The parameter influencing on speed of work and stability of an estimation. Great values increase speed of work and reduce stability of an estimation.

Rate - The parameter influencing on reliability and stability of an estimation. Great values are reasonable for using for video with the big homogeneous areas.

Margin - The size of unused edges of the image.

Brightness border - The parameter influencing reliability of an estimation. For video visually strongly polluted it is recommended to increase this parameter.

Configure algorithm details: Spatio-Temporal Gradients

spatio-temporal gradients advanced dialog box

Evaluation stability - The parameter influencing on stability of an estimation. The increase of this parameter increases stability, but reduces accuracy of an estimation.

Brightness border - The parameter influencing on reliability of an estimation. For video visually strongly polluted it is recommended to increase this parameter.


Job control & AviSynth


The filter supports Job Control, which allows to use it in AviSynth. Example:
LoadVirtualDubPlugin("...\VirtualDub\plugins\MSUNoiseEstimator.vdf","MSU_Noise_Estimator", 0)
clip=AVISource("...\clip_input.avi", false, "RGB24")
clip.ConvertToRGB32.MSU_Noise_Estimator("C:\log.csv", 0)

Parameters ケ Description Allowed values

0 File Path to log file
1 Algorithm 0 - MAD
1 - Block-Based
2 - Spatio-Temporal Gradients
3 - All algorithms


Examples


Each graph shows the examples of noise detection on 4 video sequences: the original one and 3 with noise added.


"Shattered" test sequence. Noise was added using MSU Noise Generator v2.1.


"Susie" test sequence with the removed odd frames. Noise was added using MSU Noise Generator v2.1.

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.
