MiniDeen is a spatial denoising filter. It replaces every pixel with the average of its neighbourhood.

This is a dual interface port of the VapourSynth plugin MiniDeen version beta 2.

SSE2 is required to run optimized routine. AVX2 routine is also available. Unlike VapourSynth-MiniDeen, this filter returns binary identical result between SIMD and C routine, and SIMD routine does not call C routine for pixels close to frame border.

Usage

# AviSynth+
LoadPlugin("MiniDeen.dll")
MiniDeen(clip, radiusY=1, radiusUV=1, thrY=10, thrUV=12, y=3, u=3, v=3)
# VapourSynth
core.neo_minideen.MiniDeen(clip, radius=[1,1,1], threshold=[10,12,12], planes=[0,1,2])

Parameters:

• clip

  A clip to process. It must have constant format and it must be 8..16 bit with integer samples.

• radiusY, radiusUV / radius

  Size of the neighbourhood. Must be between 1 (3x3) and 7 (15x15).

  Default: 1.

• thrY, thrUV / threshold

  Only pixels that differ from the center pixel by less than the threshold will be included in the average. Must be between 2 and 255.

  The threshold is scaled internally according to the bit depth.

  Smaller values will filter more conservatively.

  Default: 10 for the Y plane, and 12 for the other planes.

• y, u, v / planes

  Whether a plane is to be filtered.

    1 - Do not touch, leaving garbage data
    2 - Copy from origin
    3 - Process
  

  Default: 3, process all planes.

• opt

  Sets which CPU optimizations to use.

    0 - Auto detect
    1 - Use C
    2 - Use up to SSE2
    3 - Use up to AVX2
  

  Default: 0.
