File Information

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 respectively).

Gabor filters are used mostly in shape detectin and feature extractin in image processing.
1D gabor filtering reduces the filtering operations from O(M2N2) to O(MN2).

How about a 2D gabor filter ~~
How can it implement on the image?
