Dictionary Learning Phase Retrieval from Noisy Diffraction Patterns

Dictionary Learning Phase Retrieval from Noisy Diffraction Patterns

This paper proposes a novel algorithm for image phase retrieval, i.e., for recovering complex-valued images from the amplitudes of noisy linear combinations (often the Fourier transform) of the sought complex images. The algorithm is developed using the alternating projection framework and is aimed...
