<title>A Posteriori Image Restoration</title>

Abstract

Two algorithms are developed which address the problem of estimating the magnitude and phase of the optical transfer function associated with a blurred image. The primary focus of the research is on the estimate of the phase of the optical transfer function. Once an estimate of the optical transfer function has been made, the corresponding blurred image is Wiener filtered to estimate the original unblurred image (the object). Results are demonstrated on computer simulated blurs and also on real world blurred imagery.
