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. WebDaugman uniﬁes Gabor elementary functions and wavelets by deﬁning Gabor wavelets (Daugman 1993). These anisotropic (oriented) wavelets are generated from a ﬁxed Gabor elementary function (Eq. 6.17) by dilation, translation and rotation.21 Dilation, of course, also has the ancillary e↵ect of changing the frequency of the Gabor function.
