Description

Median value in an adaptive size grid is used to clean impulse noise, smooth out other noise and reduce excessive thinning of edges and for a full description click me.

Requirements

• AviSynth 2.5.8 or 2.6.0 or greater
• Supported color formats: RGB24, RGB32, YUY2, YV12, *YV16, *YV24, *YV411, *Y8

* Not available in AviSynth 2.5.8.

Syntax and Parameters

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

clip   =

Input clip.

int  sf = 0

Frame number from which this filter is to be applied.

int  ef = last frame of input clip

Frame number up to which this filter is to be applied

int  maxgrid = 5

Grid size to get statistics can grow to this value starting from 3x3. Maximum value allowed is 9.

bool  yy = true

bool  uu = false

bool  vv = false

Choose which YUV planes to process.

• True : don't process
• False : process

By default only the luma plane (Y) is processed. If the input clip is RGB, then these parameters are simply ignored.

Examples

AdaptivrMedian with default settings:

AviSource("example.avi")
AdaptiveMedian(sf=0, maxgrid=5, yy=true, uu=false, vv=false)
