This is an adaptive Median Filter for eliminating certain types of noise. It uses local statistics (minimum, maximum and median values) of a moving local grid, and changes grid size depending on local statistics. [http://www.avisynth.nl/users/vcmohan/modPlus/Median.html Full Description]

[edit] Description

This is an adaptive Median Filter for eliminating certain types of noise. It uses local statistics (minimum, maximum and median values) of a moving local grid, and changes grid size depending on local statistics. Full Description


  • For AviSynth+ see modPlus, includes high bit depth colorspace support and 64-bit.


[edit] Requirements


[edit] Syntax and Parameters

AdaptiveMedian (clip, int "sf", int "ef", int "maxgrid", bool "yy", bool "uu", bool "vv")


clip   =
Input clip.


int  sf = 0
Starting frame number to process.


int  ef =
End frame number to process, default is the last frame.


int  maxgrid = 5
Grid size to get statistics can grow to this value starting from 3x3.
Range: 3 to 9


bool  yy = true
bool  uu = false
bool  vv = false
Choose which YUV planes to process.
  • True : Do not process
  • False: Process
By default only the luma plane (Y) is processed. If the input clip is RGB, then these parameters are simply ignored.


[edit] Examples

AdaptiveMedian with default values:

AviSource("blah.avi")
AdaptiveMedian(a, maxgrid=5, yy=true, uu=false, vv=false)
