fft2dview

$ \bigcirc$Name


fft2dview Compute and Visualize the 2D-FFT of a Fimage




$ \bigcirc$Command Synopsis


fft2dview [-t type] [-s sd] [-i] [-h] [-o out] input



-t type : 0=modulus (default),1=phase,2=Re,3=Im,4=log(1+modulus)

-s sd : standart deviation for visualization (default: 50.0)

-i : to compute inverse FFT

-h : to apply a Hamming window first

-o out : to create an output Cimage instead of calling cview

input : input Fimage




$ \bigcirc$Function Summary


void fft2dview (type , sd , h_flag , in , out , i_flag )

int *type ;

float *sd ;

char *h_flag ;

Fimage in ;

Cimage out ;

char *i_flag ;




$ \bigcirc$Description


This module allows to visualize the Fast Fourier Transform of a real Fimage (or the inverse FFT is the -i option is set).
