Description

DeSaltPepper 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.


  • For AviSynth+ see modPlus, includes high bit depth colorspace support and 64-bit.


Requirements


Syntax and Parameters

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


clip   =
Input clip


string  opt = "both"
Process option:
  • "salt"
  • "pepper"
  • "both"


int  tol = 0
Tolerance limit which is not noise.
Range: -5 to 5


bool  uv = true
UV processing required?
  • true for u, v process
  • false for not processing u, v


bool  avg = true
Is average is replacement value?
  • true for average
  • false for max value of neighborhood for salt and minimum value for pepper


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


Examples

DeSaltPepper with default values: 

AviSource("blah.avi")
DeSaltPepper(opt="both", uv=true, tol=0, avg=true, feedback=3 )
