Dolphin – dictionary learning for phase retrieval

HIGHLIGHTS

  • who: Andreas Tillmann and collaborators from the (UNIVERSITY) have published the article: DOLPHIn - Dictionary Learning for Phase Retrieval, in the Journal: (JOURNAL)
  • what: - the authors propose new algorithm to learn dictionary for reconstructing and sparsely encoding signals from measurements without Specifically the authors consider the task of estimating two-dimensional image from squared-magnitude measurements of complex-valued linear transformation of the original image. The theoretical side the authors provide convergence result for the method . The authors propose a dictionary learning formulation for simultaneously solving the signal reconstruction and sparse representation problems given nonlinear, phaseless . . .
