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.

int  maxgrid = 5

Grid size to get statistics can grow to this value starting from 3x3. Maximum value allowed is 9.

bool  yy = true

bool  uu = false

bool  vv = false

Choose which YUV planes to process.

• True : don't process
• False : process

By default only the luma plane (Y) is processed. If the input clip is RGB, then these parameters are simply ignored.

Examples

Median()

a = converttoYUY2()
Median(a, maxgrid=7, yy = false, uu = true, vv = true)
