Description

DCTFun4 and DCTFun5 are both 2 fast denoisers that do hard thresholding of a complete 4x4 [2x2 for DCTFun5] ICT transform. DCTFun4 is a bit slower than DCTFun5 but should give better quality, DCTFun5 is a bit faster but less powerful in noise suppression (they are simply scaled for different speed/quality goals).

Requirements

  • AviSynth 2.5.8 or later
  • Progressive input only
  • Supported color formats: YV12


Syntax and Parameters

dctfun4b (clip, float "luma_thresh", float "chroma_thresh")
dctfun4c (clip, float "luma_thresh", float "chroma_thresh")
dctfun5 (clip, float "luma_thresh", float "chroma_thresh")


float  luma_thresh = 3.0
Luma threshold.
If it's set to 0, it bypasses the plane.


float  chroma_thresh = 2.0
Chroma threshold.
If it's set to 0, it bypasses the plane.


Examples
