AntiComb (removing combing plugin) for Avisynth

Summary

This plugin removes interlace-stripes(combing) which are not removed by Telecide(), IT(), etc .

Required software

  • Avisynth

Syntax

AntiComb(pass1=48,pass2=34,w=4,checkmode=false)

or

AntiComb(48,34,4,false)

or

AntiComb()

How to use

First, load the plugin in the avisynth script.

LoadPlugin("c:\tool\anticomb.dll")

Describe like the following below commands of other deinterlacing/IVTC plugins.

sample

telecide(choroma=true,dthreshold=13,post=false,blend=false)

anticomb()

sample

it()

anticomb()

Parameters

pass1 [Default=48]

the threshold to detects combing area.

the smaller the value is, the more sensitively anticomb detects.

the possibility to fail detecting increases if the value is too small.

pass2 [Default=34]

the threshold relates to scanning around the area detected by pass1.

if the value is set unjustly to a certain extent, maybe anticomb proceeds somehow.

the value more than pass1 is meaningless.

anticomb proceeds in 1-pass with 0.

w [Default=4]

stops digging a hole in the target area.

the big value does more effectively.

adjust when the output remains undetected area in the combing area.

checkmode [Default=false]

(This is unused by default)

To check the threshold.

This option let anticomb indicate the part of combings as violet and other parts as monochrome.

How to adjust parameters in reality

  1. search a frame which appears combings (without anticomb)
  2. insert "AntiComb(Pass1=48,Pass2=0,CheckMode?=true)" above IVTC/deinterlace filters.
  3. increase the pass1 value to a certain extent not to pick up the noise(decrease it if anticomb don't notice all part of comings).
  4. set pass2 the same as pass1, and decrease to some degree to cover the part of comings.
  5. check other frames which appears combings.
  6. remove ",CheckMode?=TRUE"

Changes

  • 2002/06/28
    • reduced the margin to 2 dots from 6 dots.
    • made combing detection routines MMX(performance improves 30 percent)
  • 2002/06/07
    • modified checking indication.
    • modified process of 1-pass.
  • 2002/06/07
    • modified to detect combings strictly / measures to deal with noise
    • checking indication were changed to coloring.
    • fixed the calculation of duplication were broken.
    • abolished reverse, threshold.
  • 2002/06/05
    • modified a part to proceed in increments of 1 dots instead of in that of 2 dots.
    • fixed that precision of duplicating was harsh.
    • controlling to dig a hole in detecting area.
    • added the changable parameter, threahold.
  • 2002/06/05
    • first version
