== Description ==
[[DeGrainMedian]] is a spatio-temporal limited median filter mainly for film grain removal, but may be used for general denoising. For additional information see the [http://avisynth.org.ru/degrain/degrainmedian.html official documentation].
 
 
== Requirements ==
* AviSynth 2.5.8 or [http://sourceforge.net/projects/avisynth2/ greater]
* Supported color formats: [[YUY2]], [[YV12]]
* SSEMMX ([[ISSE|Integer SSE]]) capable CPU

===Limitations===
*No scenechange detector in current version. But I do not see any ghosting - filter is switched to spatial pixel pairs.
*First and last line (line pair for interlaced) of every frame are not filtered.
*First and last 8 (YV12) or 4 (YUY2) pixels in every row are filtered with more simple (same columns) method.
*Chroma filtering in YUY2 mode is also in same columns only.
*First and last frames are not filtered.
 
== [[Script variables|Syntax and Parameters]] ==
:{{Template:FuncDef|DeGrainMedian (clip, int "limitY", int "limitUV", int "mode", bool "interlaced", bool "norow" )}}
 
::{{Par2| |clip| }}
:::Input clip.
 
::{{Par2|limitY|int|4}}
::{{Par2|limitUV|int|6}}
:::Limit of pixel luma(Y) and chroma(UV) correction (0 to 255).
 
::{{Par2|mode|int|1}}
:::Operation mode (0 to 5, the more, the weaker)
 
::{{Par2|interlaced|bool|false}}
:::Process clip as interlaced.
 
::{{Par2|norow|bool|false}}
:::Do not use same row in spatial filter.
 

== Examples ==
DeGrainMedian with all default values:
[[AviSource]]("Blah.avi")
DeGrainMedian(limitY=4, limitUV=6, mode=1, interlaced=false, norow=false)
 
== Changelog ==
Version Date(D/M/Y) Changes
