Fourier Transform Functions
FFT Returns an image pair of the Fourier transform coefficients of the input image
InvFFT Returns an image calculated using the inverse Fourier transform on the input FFT coefficient image pair
ViewFFT Returns the pair of input images after they have been normalised using a log scale, to improve their legibility
FFTAdaptiveLP Returns the input pair of images after a ceiling threshold on the input image values has been applied, reducing the effect of high response frequencies
FFTGaussian Returns an image pair of the user specified size, which are the FFT coefficients of an image of a gaussian kernel with the user specified standard deviation
FFTDivide Returns an image pair of the division of the first input coefficient images, by the second input coefficient images
FFTMultiply Returns an image pair of the multiplication of the first input coefficient images, by the second input coefficient images
FFTLowPass Returns an image pair of the user specified low frequency portion of the input image pair
FFTHighPass Returns an image pair of the user specified high frequency portion of the input image pair
FFTBandPass Returns an image pair of the user specified mid frequency portion of the input image pair
FFTBandStop Returns the input image pair with the user specified mid frequency portion of the input image pair set to zero
FFTSelectivePass Returns the input image pair with a user specified portion of the input image pair set to zero
