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

• YV12

Syntac 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")

luma_thresh float = 3.0

Luma threshold.

If it's set to 0, it bypasses the plane.

chroma_thresh float = 2.0

Chroma threshold.

If it's set to 0, it bypasses the plane.
