filter_gabor_2D

PURPOSE ^

2D Gabor filters.

SYNOPSIS ^

function [Feven,Fodd]=filter_gabor_2D(r,sig,lam,theta,show)

DESCRIPTION ^

 2D Gabor filters.

 Creates a pair of Gabor filters (one odd one even) at the specified orientation.  
 For Thomas' ECCV98 filters, use sig=sqrt(2), lam=4.

 INPUTS
   r       - final mask will be 2r+1 x 2r+1
   sig     - standard deviation
   lam     - elongation 
   theta   - orientation
   show    - [optional] figure to use for display (no display if == 0)

 OUTPUTS
   Feven   - even symmetric filter (-cosine masked with Gaussian)
   Fodd    - even symmetric filter (-sine masked with Gaussian)

 EXAMPLE
   [Feven,Fodd]=filter_gabor_2D(15,sqrt(2),4,45,1);
