Description
This function, formerly named HistogramAdjust but now named TweakHist, 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
- TweakHist(clip, int type, clip mclip, int mf, int limit, int rgb )
- clip =
- Input clip.
- clip =
- int =
- Luma value % of maximum.
- int =
- clip =
- % age of population or cumulative population at this luma value
- clip =
- type int = 1
- Type of process
- type int = 1
- mclip clip = dummy clip
- Clip in which image for matching is available.
- mclip clip = dummy clip
- 0 mf =
- Frame number on clip for matching.
- 0 mf =
- limit int = 100
- Limit on % of change in value from original for tweaking allowed.
- limit int = 100
- rgb int = 1
- Percentage of deviation from original value of luma to be allowed.
- rgb int = 1
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)
