[edit] Description
A plugin with 5 different types of median blur filters.
[edit] Requirements
- AviSynth 2.5.8 or later
- Progressive input only
- Supported color formats: YV12
[edit] Filters
| Filter | Description | Color format |
|---|---|---|
| MedianBlur |
A spatial median blur filter with a variable radius. |
YV12 |
| MedianBlurB |
A binary median blur filter. It will take advantage of integer SSE if present. |
YV12 |
| MedianBlurCW |
A centerweighted median blur filter with a variable radius. |
YV12 |
| MedianBlurT |
A temporal-spatial median blur filter with optional motion compensation using Manaos MVTools. |
YV12 |
| ML3Dex |
ML3Dex means Extended Multi Level 3Dimensional filtering. |
YV12 |
[edit] Common Parameters
int radiusy = 2
int radiusu = 2
int radiusv = 2
- Specify the radius to use:
- If the supplied radius is between -1 and -255 the plane is set to -radius.
- If the the radius is 0 the plane is copied unaltered.
- If the radius is less than -255 the plane isn't processed at all.
- Default is 2.
bool calcborder = true
- If true (default) the borders of the frame is filtered too.
- If false then the border is copied from the source clip.
[edit] Changelog
Version Date Changes
0.84 03/19/2005 - Added the option searchparam, bsfull, and spfull to ML3Dex and MedianBlurT.
0.83 12/05/2004 - Fixed a bug that caused a memory leak with motion compensation. - Now calls MVTools with named arguments. This should increase support of different versions of MVTools.
0.82 - Fixed a bug that caused an access violation in MedianBlurT and ML3Dex.
0.81 - Bug fixes and added an option to show when MVTools detects a scene change.
0.8 - Added ML3Dex a multilevel temporal median blur filter that can use MVTools for motion compensation.
0.7 - Added support for motion compensation in MedianBlurT using manao's MVTools.
0.65 - More bugs removed. - Added assembler optimization resulting in 30-60% speed increase for MedianBlurCW, MedianBlurT and MedianBlur(for radius >3)
0.6 - Fixed a couple of bugs and added integer SSE optimization for MedianBlur for radius below 4. This results in a 85-400% speed increase.
0.5 - Added MedianBlurB and MedianBlurT.
0.4 - Added MedianBlurCW, a centerweighted median blur.
0.31 - bugfix. Should make the same output as TMedianBlur except for the borders.
0.3 - Optimized the sort algorithm even more. Also added the ability to process the borders.
0.2 - Changed the sort algorithm to radix sort resulting in a great speed improvement especially for large radii. - Also fixed a couple of bugs.
0.1 10/29/2004 - First version. Really slow and buggy. - Used a modified bubble sort to find the median causing the filter to be extremely slow with large radii.
