[edit] Description

A really simple mask cleaning plugin for AviSynth based on mt_hysteresis. It discards all areas of less than length pixels with values bigger or equal to thresh.

[edit] Requirements

• [x86]: AviSynth+ or AviSynth 2.6
• [x64]: AviSynth+
• Supported color formats: Y8, YV12, YV16, YV24
• Microsoft Visual C++ 2012 Redistributable Packages

[edit] Syntax and Parameters

TMaskCleaner (clip, int "length", int "thresh", int "fade")

clip   =

Input clip.

int  length = 5

int  thresh = 235

It discards all areas of less than length pixels with values bigger or equal to thresh.

int  fade = 0

Usage: TMaskCleaner(length=100, fade=200) will zero areas below length, assign 0..255 to areas in [length,length+fade] range, and 255 to areas above length+fade.

This allows adaptive processing of area ranges for example by transforming the mask from linear 0..255 distribution denoted here as / to:

• /\ with mt_lut("x 128 > 255 x - x ?")
• || to grab some arbitrary range with mt_lut("x 118 > x 138 < & 255 0 ?")
• non-linear _/_ mask by smoothly amplifying the middle with mt_lut("x 128 > 255 x - x ? 100 - 28 / 0.5 ^ 256 *")

[edit] Examples

TMaskCleaner with default values:

AviSource("bah.avi")
TMaskCleaner(length=5, fade=235, fade=0)
