Abstract

A multiresolution approach for image reconstruction from the magnitude of its Fourier transform has been developed and implemented by employing the concept of pyramid sampling. In this approach several iterations of the error reduction algorithm are preformed at each level of the pyramid using a coarse-to-fine strategy, resulting in improved convergence and reduced computational cost.
