Description

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

Usage

lghost.LGhost(clip clip, int[] mode, int[] shift, int[] intensity[, int planes, int opt=0])

• clip: Clip to process. Any planar format with either integer sample type of 8-16 bit depth or float sample type of 32 bit depth is 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).

• planes: Sets which planes will be processed. Any unprocessed planes will be simply copied. By default only luma plane is processed for non-RGB formats.

• opt: Sets which cpu optimizations to use.

  • 0 = auto detect
  • 1 = use c
  • 2 = use sse2
  • 3 = use avx2
  • 4 = use avx512

Each ghost consists of individual value from mode, shift and intensity. For example, lghost.LGhost(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.
