Primary Contents

Scripts:

  • PR_demo.m: Demonstrates phase retrieval from noisy coded diffraction and fourier measurements using prDeep.

Functions:

  • prDeep.m: Implementation of prDeep
  • HIO.m: Basic implementation of HIO algorithm

Auxiliary functions:

  • disambig2Drfft.m: Phaseless 2D fourier transforms have phase and translation ambiguities. This function accounts for them.

Packages

This download includes trained DnCNN denoiser weights for various noise levels.
