WitrynaOne of the most widely used stimuli in psychophysics is the gabor. A gabor is a grating whose contrast is modulated by a gaussian envelope. In this tutorial you will add the gaussian envelope to the existing stimulus to transform it from a … To use Gabor magnitude responses as features for use in classification, some post-processing is required. This post processing includes Gaussian smoothing, adding additional spatial information to the feature set, reshaping our feature set to the form expected by the pca and kmeansfunctions, and … Zobacz więcej Read and display the input image.

WitrynaFor test stimuli we used matrix of Gabor grating. We used two types of 10 x 10 matrices with chaotic and ordered orientation of Gabor gratings. The size, brightness and contrast of the stimuli were identical. The chaotic and ordered patterns activated different brain areas. We establish that ordered patterns activated only primary visual cortex ...
