MatchHistogram

Revision as of 15:35, 17 June 2020

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

• [x86]: AviSynth+ or AviSynth 2.6
• [x64]: AviSynth+
• Supported color formats: Y8, YV12, YV16, YV24

• Microsoft Visual C++ 2019 Redistributable Package (x86 / x64)

*** 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.
