Description

frfun7 is a spatial fractal denoising plugin.

Note: frfun7 2013 is the updated version, unfortunately the output is not identical to frfun7_rev6. For that reason both versions are available.

Requirements

- AviSynth 2.5.8 or later

- Progressive input only

- Supported color formats: YV12

• frfun7 2013 only:

- Microsoft Visual C++ 2010 Redistributable Package (x86)

Syntax and Parameters

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

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 : default; fast but can create some minor artifacts around line edges. Quality is slightly inferior to frfun7_rev6.
• 1 : much slower but the quality is a little bit better than frfun7_rev6.

Examples

frfun7 with default settings:

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