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.
