WebMay 29, 2024 · The profile of the receptive field of these simple cells can be mathematically described by a Gabor function [7]. A Gabor function is defined as the product of a sinusoid function and a Gaussian envelope (Box 1). Apart from describing the profile of the receptive field, Gabor functions also form Gabor patterns or patches. WebYou can use the gabor function to create a single Gabor filter or a Gabor filter bank. A filter bank is a set of filters that represent combinations of multiple wavelengths, orientations, and other optional parameters.
