filter_gabor_1D

PURPOSE ^

1D Gabor Filters.

SYNOPSIS ^

function [feven,fodd] = filter_gabor_1D( r, sig, omega, show );

DESCRIPTION ^

 1D Gabor Filters.

 Creates a pair of 1D Gabor filters (even/odd).

 INPUTS
   r       - final mask will be 2r+1 (good choice for r is r=2*sig)
   sig     - standard deviation of Gaussian mask
   omega   - frequency of underlying sine/cosine 
             should range between 1/(2r+1) and r/(2r+1)~.5 
             otherwise false frequencies form
   show    - [optional] figure to use for display (no display if == 0)

 OUTPUTS
   feven   - even symmetric filter (-cosine masked with Gaussian)
   fodd    - odd symmetric filter (-sine masked with Gaussian)

 EXAMPLE
   tau = 5; filter_gabor_1D(2*tau,tau,1/tau,1);
