Impulsive noise appears on images either as relatively white (salt) or as relatively black dots (pepper)and such noises are cleaned by this plugin and a full description is at  [http://www.avisynth.nl/users/vcmohan/DeSaltPepper/DeSaltPepper.html click me].

Description

The function SaltPepper uses morphology technique to identify such noise and replace those pixels by average or minimum or maximum whichever is appropriate of the surrounding pixels. Full Description.


Requires AviSynth+ r2347 or greater

Syntax and Parameters

DeSaltPepper(clip, string "opt", bool "uv ",bool avg", int "feedback")


clip   =
Input clip.


opt  string = "both"
Option of process.


uv  bool = true
UV processing required?


avg  bool = true
Is average is replacement value?


feedback  int = 0
Number of feed back loops in processing to be used. applicable only if avg is true. 0 to 10.


Examples 

SaltPepper(img, opt = "both",UV = true, tol = 0, avg = true, feedback = 3 ) 

ds = SaltPepper(img, opt = "both",UV = true)
ds1 = SaltPepper(img, opt = "salt",UV = false, avg = false)
ds2 = SaltPepper(ds1, opt = "pepper",UV = true)
