Method Detail

createGaborJets

public static FImage[] createGaborJets(int width,
                                       int height,
                                       int... orientationsPerScale)

Create a jet of (multiscale) Gabor filters in the frequency domain. The returned filters have the highest frequency in the centre; to apply them to an image, use FourierConvolve.convolvePrepared(FImage, FImage, boolean) with the third argument set to true.

Parameters:

width - the width of the image that will be filtered (note that the returned filters will have twice this width to account of the imaginary (phase) values [all of which are zero])

height - the height of the image that will be filtered

orientationsPerScale - the number of filter orientations for each scale (from HF to LF)

Returns:

the jet of filters
