(`fourier_shift``input, shift, n=-1, axis=-1, output=None`)-
The
`fourier_shift`function multiplies the input array with the multi-dimensional Fourier transform of a shift operation for the given shift. The`shift`parameter is a sequences of shifts for each dimension, or a single value for all dimensions.

(`fourier_gaussian``input, sigma, n=-1, axis=-1, output=None`)-
The
`fourier_gaussian`function multiplies the input array with the multi-dimensional Fourier transform of a Gaussian filter with given standard-deviations`sigma`. The`sigma`parameter is a sequences of values for each dimension, or a single value for all dimensions.

(`fourier_boxcar``input, size, n=-1, axis=-1, output=None`)-
The
`fourier_boxcar`function multiplies the input array with the multi-dimensional Fourier transform of a boxcar filter with given sizes`size`. The`size`parameter is a sequences of values for each dimension, or a single value for all dimensions.

(`fourier_ellipsoid``input, size, n=-1, axis=-1, output=None`)-
The
`fourier_ellipsoid`function multiplies the input array with the multi-dimensional Fourier transform of a elliptically shaped filter with given sizes`size`. The`size`parameter is a sequences of values for each dimension, or a single value for all dimensions.**Note:**This function is only implemented for dimensions 1, 2, and 3.
