== Description ==
[[DePulse]] reduces the white noise that gets in the image. It seems to be the noise of the old fluorescent lamp or the engine of the motorcycle.

'''[[DePulse#DePulseC|DePulseC]]''' is sister product of [[DePulse]]. Just applying the same algorithm to the color difference. Reduces color pulse noise. Integrate with DePulse.



'''NOTE: documentation was translated from the Japanese readme.'''

 
== Requirements ==
* [x86]: [[AviSynth+]] or [https://sourceforge.net/projects/avisynth2/ AviSynth 2.5.8 or greater]
*Supported color formats: [[YUY2]]
*Top field interlacing only

===DePulse===
:{{Template:FuncDef|DePulse (clip, int "h", int "l", int "d", bool "debug")}}
 
::{{Par2| |clip| }}
:::Input clip.
 
::{{Par2|h|int|180}}
:::Luminance below <code>h</code> is not subject to white noise.
:::Range: 0-255
 
::{{Par2|l|int|60}}
:::Luminance above <code>l</code> is not subject to black noise.
:::Range: 0-255
 
::{{Par2|d|int|30}}
:::If the brightness is different from the pixels in the front and back (upper and lower) fields for <code>d</code> or more, it is determined as noise. (Common for white and black noise).
:::Range: 0-255
 
::{{Par2|debug|bool|false}}
:::When debug is set to true, pink and green color will be added to the part determined as white and black noise.
 
===DePulseC===
:{{Template:FuncDef|DePulseC (clip, int "h", int "l", int "d", bool "debug")}}
 
::{{Par2| |clip| }}
:::Input clip.
 
::{{Par2|h|int|180}}
:::Color differences less than <code>h</code> are not subject to color noise.
:::Range: 0-255
 
::{{Par2|l|int|60}}
:::Color differences greater than <code>l</code> are not subject to color noise.
:::Range: 0-255
 
::{{Par2|d|int|30}}
:::If the color difference between the pixels in the front and back (upper and lower) fields is more than <code>d</code>, it is determined as noise. (Common for white and black noise).
:::Range: 0-255
 
::{{Par2|debug|bool|false}}
:::When debug is set to true, the part determined as color noise becomes white and black.
 

== Examples ==
DePulse with default settings:
[[AviSource]]("Blah.avi")
DePulse (h=180, l=60, d=30, debug=false)

DePulseC with default settings:
[[AviSource]]("Blah.avi")
DePulseC (h=180, l=60, d=30, debug=false)
*DePulseC Hint: First, adjust <code>h</code> to around <code>h=50</code>, <code>l=200</code> and adjust <code>d</code> (about 20 to 50?). You may have some side effects. After that, gradually increase <code>h</code> and lower <code>l</code> to reduce side effects.
