Figure 6From: A sub-Riemannian model of the visual cortex with frequency and phaseTop: Real part of a Gabor function (left) and its rotated version (middle right) together with their counterparts in the spectral domain in the same order (right and middle right). Orange arrows highlight the rotation angle. Middle: Set of rotated Gabor functions (in the spectral domain) corresponding to the frequency values \(\omega =1,2,3\) in the same order from left to right. Bottom: The set of rotated Gabor functions in the spectral domain where the number of orientation samples are 8 and 16 rotation anglesBack to article page
