Description
This is an adaptive Median Filter for eliminating certain types of noise. It uses local statistics (minimum, maximum and median values) of a moving local grid, and changes grid size depending on local statistics. Full Description
Requirements
- AviSynth+ r2347 or later
Syntax and Parameters
- Median (clip, int "maxgrid", bool "yy", bool "uu", bool "vv")
- clip =
- Input clip.
- clip =
- int maxgrid = 5
- Grid size to get statistics can grow to this value starting from 3x3.
- Maximum value allowed is 9.
- Grid size to get statistics can grow to this value starting from 3x3.
- int maxgrid = 5
Examples
Median()
a = converttoYUY2() Median(a, maxgrid=7, yy = false, uu = true, vv = true)
