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); DATESTAMP 29-Sep-2005 2:00pm See also FILTER_GABOR_2D
