Description

This function adjusts the histogram of a frame by either equalizing it or by matching with histogram of another image, or with given histogram table of values. Full Description


Requirements

  • AviSynth+ r2347 or greater
  • Source video: Progressive


Syntax and Parameters

GBlur (clip, int "rad", float "sd", bool "u", bool "v")


clip   =
Input clip.


int  rad = 3
Radius of grid to use between 3 to 8.


float  sd = 1.5
Standard deviation.


bool  u = false
Is u plane smoothing required?


bool  v = false
Is v plane smoothing required?



Examples 

TweakHist() 
TweakHist(c,type=2,mclip=mm,mf=26)
TweakHist(c,15,2, 30,12, 50, 33, 90, 12,150,35,200,10, type=3,limit=50)
TweakHist(20,1,150,100,255,110, type=4,limit = 70)
RGB input. Repeated for each color 
TweakHist(limit = 70,rgb = 0)
TweakHist(limit = 70,rgb = 1)
TweakHist(limit = 50, rgb = 2)
