DePulse

Revision as of 05:44, 1 June 2020

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.

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 AviSynth 2.5.8 or greater
• Supported color formats: YUY2
• Top field interlacing only

Syntax and Parameters

DePulse

DePulse (clip, int "h", int "l", int "d", bool "debug")

clip   =

Input clip.

int  h = 180

Luminance below h is not subject to white noise.

Range: 0-255

int  l = 60

Luminance above l is not subject to black noise.

Range: 0-255

int  d = 30

If the brightness is different from the pixels in the front and back (upper and lower) fields for d or more, it is determined as noise. (Common for white and black noise).

Range: 0-255

bool  debug = false

When debug is set to true, pink and green color will be added to the part determined as white and black noise.

DePulseC

DePulseC (clip, int "h", int "l", int "d", bool "debug")

clip   =

Input clip.

int  h = 180

Color differences less than h are not subject to color noise.

Range: 0-255

int  l = 60

Color differences greater than l are not subject to color noise.

Range: 0-255

int  d = 30

If the color difference between the pixels in the front and back (upper and lower) fields is more than d, it is determined as noise. (Common for white and black noise).

Range: 0-255

bool  debug = 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 h to around h=50, l=200 and adjust d (about 20 to 50?).
  You may have some side effects. After that, gradually increase h and lower l to reduce side effects.
