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.

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.
