Set projection algorithms for blind ptychographic phase retrieval

Abstract

Set projection algorithms are a class of algorithms used in ptychography to help improve the quality of the reconstructed images. The set projection step is important because it helps to ensure that the reconstructed image satisfies the physical constraints, which can improve the quality of the final result. A new projection algorithm that combines the advantages of the existing algorithms is proposed and offers the possibility of a parallel algorithm for iterative algorithms.Comment: Presented in ISCS2
