Creates an even/odd pair of 1D Gabor filters. USAGE [feven,fodd] = filterGabor1d( r, sig, omega, [show] ) INPUTS r - final filter will be 2r+1 (good choice for r is r=2*sig) sig - standard deviation of Gaussian mask omega - frequency of underlying sine/cosine in [1/(2r+1) r/(2r+1)] show - [0] figure to use for optional display OUTPUTS feven - even symmetric filter (-cosine masked with Gaussian) fodd - odd symmetric filter (-sine masked with Gaussian) EXAMPLE sig = 15; f=filterGabor1d(2*sig,sig,1/sig,1); See also FILTERGABOR2D Piotr's Computer Vision Matlab Toolbox Version 2.0 Copyright 2014 Piotr Dollar.
