Recent studies on Mathematical modeling of visual cortical cells [Kulikowski/Marcelja/Bishop:1982] suggest a
tuned band pass filter bank structure. These filters are found to have Gaussian transfer functions in the
frequency domain. Thus, taking the Inverse Fourier Transform of this transfer function we get a filter
characteristics closely resembling to the Gabor filters. The Gabor filter is basically a Gaussian (with variances sx
and sy along x and y-axes respectively) modulated by a complex sinusoid (with centre frequencies U and V
along x and y-axes respectivel
