Description

Regular frequency interference on images. These can be attenuated with either 1D or 2D frequency filters. Frequency spectral displays enable to find such interference and design correcting filters. Full Description

Requirements

• AviSynth+ r2347 or greater
• libfftw3f-3.dll, FFTw3.dll, or fftw.dll

Syntax and Parameters

FnQuiver (clip, int array "", bool "test", bool "morph ",float gamma",Effect_specific_parameters")

clip   =

Input clip.

  int array = none

Array of integer sets specifying frequency domain filters .May not specify for test mode.

test  bool = false

If true display power spectrum and designed filters .

morph  bool = false

Is homomorphic filtering intended? .

gamma  float = 0.05

scaling for spectral display .

refer_specific_function  * = ?

See detailed description of functions.
