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. gully\u0027s hfWitryna18 gru 2024 · gabor_feature_engine. The gabor_feature_engine method is an extension of the initial Matlab code and allows the user to extract gabor features from multiple images.
