"Witryna26 sie 2015 · Gabor filters were originally introduced as an acoustic (1D) filter to explain audition. A Gabor filter is a product of the Gaussian envelope and the (complex) sinusoidal carrier: Remember, e i x = cos x + i sin x; so the filter has both real and imaginary parts. Exercise 1. Let’s create some 2D Gabor filters and visualize them. " - Import gaborgrating from gabor-grating
