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. Witryna2 cze 2024 · Gabor Feature Extraction. This program generates a custom Gabor filter bank; and extracts the image features using them. The first function named …

The drifting grating stimulus consists of a full-field sinusoidal grating that drifts in a direction perpendicular to the orientation of the grating. In this experiment, the grating drifts in one of eight directions, at 45° intervals, and at one of five temporal frequencies, ranging from 1 to 15 cycles per ... how to return value from stored procedure
