Description

Luminance Ghost reduction filter. Can be used for removing luminance ghost or edge ghost (ringing).

This is a port of the VapourSynth plugin LGhost.

Requirements:

• AviSynth+ 3.6 or later

• Microsoft VisualC++ Redistributable Package 2022 (can be downloaded from here)

Usage:

vsLGhost (clip, int[] mode, int[] shift, int[] intensity, int "y", int "u", int "v", int "opt")

Parameters:

• clip
  A clip to process. All planar formats are supported.

• mode
  Ghost removal mode.
  1: Edge.
  2: Luminance.
  3: Rising edge.
  4: Falling edge.

• shift
  Width to shift.
  Must be between -width and width (exclusive).

• intensity
  Strength.
  Must not be 0 and must be between -128 and 127 (inclusive).

• y, u, v
  Planes to process.
  1: Return garbage.
  2: Copy plane.
  3: Process plane. Always process planes when the clip is RGB.
  Default: y = 3; u = v = 2.

• opt
  Sets which cpu optimizations to use.
  -1: Auto-detect.
  0: Use C++ code.
  1: Use SSE2 code.
  2: Use AVX2 code.
  3: Use AVX512 code.
  Default: -1.

Each ghost consists of individual value from mode, shift and intensity. For example, vsLGhost(mode=[2, 2, 1, 1], shift=[4, 7, -4, -7], intensity=[20, 10, -15, -5]) corresponds to four ghosts. The first ghost is (mode=2, shift=4, intensity=20), the second ghost is (mode=2, shift=7, intensity=10), and so on.
