:module: std
|

|
|
|
||
|
|
Replaces each pixel with the median of the nine pixels in its 3x3
|
||
|
|
neighbourhood. In other words, the nine pixels are sorted from lowest
|
||
|
|
to highest, and the middle value is picked.
|
||
|
|
|
||
|
|
*clip*
|
||
|
|
Clip to process. It must have integer sample type and bit depth
|
||
|
|
between 8 and 16, or float sample type and bit depth of 32. If
|
||
|
|
there are any frames with other formats, an error will be
|
||
|
|
returned.
|
||
|
|
|
||
|
|
*planes*
|
||
|
|
Specifies which planes will be processed. Any unprocessed planes
|
||
|
|
will be simply copied.
