Description

MatchHistogram modifies one clip's histogram to match the histogram of another clip.

Will produce weird results if frame contents are dissimilar.

Should be used for analysis only, not for production.

Requirements


*** vcredist_x86.exe required for MatchHistogram-x86
*** vcredist_x64.exe required for MatchHistogram-x64


Syntax and Parameters

MatchHistogram (clip clip1 , clip clip12, clip clip3, bool "raw", bool "show", bool "debug", int "smoothing_window", bool "y", bool "u", bool "v")


clip   =
Clip1: must have constant format and dimensions and 8 bits per sample, and it must not be RGB.


clip   =
Clip2: clip whose histogram is to be copied.
Must have the same format and dimensions as clip1.


clip   = clip1
Clip3: clip to be modified to match clip2's histogram.
Must have the same format as clip1 and constant dimensions.
If this parameter is not passed then clip1 is used instead.
Default: clip1


bool  raw = false
Use the raw histogram without postprocessing.


bool  cpu = false
Show calculated curve on video frame.
This parameter has no effect when debug=true.


bool  debug = false
Return 256x256 clip with calculated data.


int  smoothing_window = 8
Window used when smoothing the curve.
A value of 0 disables the smoothing.
This parameter has no effect when raw=true.


bool  y = true
bool  u = false
bool  v = false
Select which planes to process. Any unprocessed planes will be copied from the third clip.
