Fast algorithms for bispectral reconstruction of two-dimensional signals

Algorithms are developed to reconstruct the phase and magnitude of the Fourier transform of a two-dimensional, discrete, deterministic signal from samples of its bispectrum B(ω,λ). The samples are derived from the plane ω-λ. The techniques involve finding the DFTs (discrete Fourier transforms) of the phase and magnitude of the bispectrum samples, and from them, recovering samples of the phase and magnitude of the Fourier transform of the signal at select frequencies
