Web29 de out. de 1997 · Abstract: The 2-D discrete phase retrieval problem is to reconstruct a discrete-time signal whose support is known and compact from the magnitude of its discrete Fourier transform. We show how a subband decomposition of this problem can be performed using filter banks. The result is a series of smaller 2-D phase retrieval …
Web6 de jan. de 2016 · The use of a “window” 2D Hilbert transform for reconstruction of the phase distribution of remote objects is proposed. It is shown that the advantage of this approach consists in the invariance of a phase map to a change of the position of the kernel of transformation and in a possibility to reconstruct the structure-forming elements of the … Webability we only define the phase retrieval problems for one-dimensional signals. The extension to higher dimensions is straight forward. A.
