[edit] Description

BucketMedian is an implementation of spatial median filter adapting bucket (counting) sort algorithm. Also induces BMBorderProc.avsi, a script to safely process borders with BucketMedian.

[edit] Requirements

** AviSynth 2.5.8 only supports YV12



[edit] Syntax and Parameters

BucketMedian (clip, int "radius", int "thresh", int "min", int "max")


clip   =
Input clip; only planar formats are supported and only luma will be processed.


int  radius = 1
The radius of the neighborhood pixel referred to in order to calculate a median.
Higher values require heavy resources. Box size is (radius*2+1) * (radius*2+1).
Range: 1 to 255


int  thresh = 1
Threshold of which determines whether to change a pixel value into a median.
new = absolute(median - old) < thresh ? median : old
(new:filtered pixel value, old:source pixel value)
Range: 1 or higher


int  min = 0
Threshold of low pixel value.
If source's value is lower than this, the pixel is not processed.
Range: 0 to 254


int  max = 255
Threshold of high pixel value.
If source's value is higher than this, the pixel is not processed.
Range: 1 to 255


[edit] Examples

MedianBucket with default settings: 

AviSource("blah.avi")
MedianBucket(radius=1, thresh=1, min=0, max=255)
