Numerical Optimization Algorithm of Wavefront Phase Retrieval from Multiple Measurements
Ji Li, Tie Zhou
Wavefront phase retrieval from a set of intensity measurements can be formulated as an optimization problem. Two nonconvex objective models (MLP and its variants LS) based on maxim…

On Gradient Descent Algorithm for Generalized Phase Retrieval Problem
Ji Li, Tie Zhou
In this paper, we study the generalized phase retrieval problem: to recover a signal from the measurements $y_r=\lvert \langle\bm{a}_r,\bm{x}\rangle\rvert^2…

Superiorization of EM Algorithm and Its Application in Single-Photon Emission Computed Tomography(SPECT)
Shousheng Luo, Tie Zhou
In this paper, we presented an efficient algorithm to implement the regularization reconstruction of SPECT. Image reconstruction with priori assumptions is usually modeled as a con…
