Description

frfun7 is a spatial fractal denoising plugin.

Note: frfun7 2013 is the updated version, unfortunately the output is not completely identical to frfun7_rev6, for that reason both versions are available. Read description of the P parameter for more information.

Requirements

• [x86]: AviSynth+ or AviSynth 2.5.8 or greater
• Progressive input only
• Supported color formats: YV12

• frfun7 2013 only: Microsoft Visual C++ 2010 Redistributable Package (vcredist_x86.exe)

Syntax and Parameters

frfun7 (clip, float "lambda",float "T", float "Tuv", int "P")

clip   =

Input clip.

float  lambda = 1.1

Adjust the power of the local denoising.

float  T = 10.0

Limits the max luma denoising power for edges; 0 disables processing.

float  Tuv = 2.0

Limits the max chroma denoising power for edges; 0 disables processing.

int  P = 0

Undocumented parameter, only available in frfun7 2013. By testing, one can conclude it's a "speed -vs- quality" trade off setting.

• 0 : faster but slightly lower quality than frfun7_rev6 (may create minor artifacts around line edges).
• 1 : slower than frfun7_rev6 but the quality is a little bit better.

Examples

frfun7 with default settings:

AviSource("Blah.avi")
frfun7(lambda=1.1, T=6.0, Tuv=2.0, P=0)
