AdaptiveMedian

[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

• [x86]: AviSynth+ or AviSynth 2.6
• Supported color formats: RGB24, RGB32, YUY2, Y8, YV12, YV16, YV24

[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)
