The following is an example of a two-dimensional Gabor function which contains horizontal stripes. To make the stripes vertical, exchange X's and Y's. Gabor function may also use sin rather than cos.
2 -2.77 x (X-Xo) f(X,Y) = Amplitude x exp( ---------------- ) 2 Wx 2 -2.77 x (Y-Yo) x exp( ---------------- ) 2 Wy x cos(2 x pi x f x (Y-Yo)+ p)
