Abstract
Reconstruction from phase information via convex projections is considered for deblurring smeared images when the blurring function does not introduce any phase. The effects of initialization and constraints in the algorithm are investigated. It is shown by examples that the number of quantization levels when the smeared image is digitized determines the quality of the restored image.
