"ci*[type]s[table]b[mclip]c[mf]i[window]b[w]i[h]i[limit]i"

Syntax and Parameters

HistogramAdjust(clip, int array "", string "type", bool "table ",clip mclip",int mf",bool window",int w",int h",int limit")

clip   =

Input clip.

  int array =

table of luma and population pairs in case table is true .

type  string = "equal"

"equal" or "match"

table  bool = false

Whether table of values are specified for matching Histogram.

mclip  clip = clip

Clip with which input clip histogram is to be matched .

mf  int = 0

frame number of mclip with which clip histogram is to be matched .

window  bool = false

Whether windowed equalization is to be done .

w  int = frame width/4

If window is true, width of window (odd number) to be used.

h  int = frame height/4

If window is true, height of window (odd number) to be used.

limit  int = 100

percentage of deviation from original value of luma to be allowed .

Examples

## This is some example code to blur  an image.
imagereader("C:\..........jpg", end = 10)
a = avisource("C;\..........avi").converttoYUY2()
converttoyv16()
# HistogramAdjust matching with given table
m1=HistogramAdjust(1,250,100,570,200,0,type="match",table=true, window=false,w=259,h=255)
# matching with an image on a frame of another clip
h2 = HistogramAdjust(type="match",table=false, mclip=a ,mf=1)
# Histogram equalization
HistogramAdjust()
# equalization with limit
h1 = HistogramAdjust( limit = 80)
