Functions

void dip::FourierTransform(dip::Image const& in, dip::Image& out, dip::StringSet const& options = {}, dip::BooleanArray process = {})

Computes the forward and inverse Fourier Transform

void dip::InverseFourierTransform(dip::Image const& in, dip::Image& out, dip::StringSet options = {}, dip::BooleanArray process = {})

Inverse Fourier Transform. Convenience function that calls dip::FourierTransform after adding “inverse” to options.

auto dip::OptimalFourierTransformSize(dip::uint size, dip::String const& which = S::LARGER, dip::String const& purpose = S::REAL) -> dip::uint

Returns the next larger (or smaller) multiple of small integers. An image of this size is more efficient for FFT computations.

void dip::RieszTransform(dip::Image const& in, dip::Image& out, dip::String const& inRepresentation = S::SPATIAL, dip::String const& outRepresentation = S::SPATIAL, dip::BooleanArray process = {})

Computes the Riesz transform of a scalar image.

void dip::StationaryWaveletTransform(dip::Image const& in, dip::Image& out, dip::uint nLevels = 4, dip::StringArray const& boundaryCondition = {}, dip::BooleanArray const& process = {})

Computes a stationary wavelet transform (also called à-trous wavelet decomposition).

void dip::HaarWaveletTransform(dip::Image const& in, dip::Image& out, dip::uint nLevels = 4, dip::String const& direction = S::FORWARD, dip::BooleanArray process = {})

Computes the Haar wavelet transform or its inverse.
