[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.
- clip =
- 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).
- int radius = 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)
- int thresh = 1
- 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.
- int min = 0
- 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.
- int max = 255
- Range: 1 to 255
[edit] Examples
MedianBucket with default settings:
AviSource("blah.avi") MedianBucket(radius=1, thresh=1, min=0, max=255)
[edit] Changelog
Version Date Changes
v0.3.0 08/21/2012 - Remove border processing and add BMBorderProc.avsi v0.2.0 04/06/2012 - Add "thresh" parameter v0.1.0 04/04/2012 - Initial release
