Paper Abstract

Greatly sharpened images may be extracted from photographs which have been blurred either by accident or deliberately (for instance when coded in view of special image processing applications). In simple words, it has recently become truly possible to turn a bad photograph into a good image in a great number of situations, notably those of interest in space imaging. Examples in the first category (accidentally blurred) include photographs blurred by motion, imperfect focus, instrumental defects and by atmospheric turbulence, among other causes. Examples of the second category (deliberately coded) include the synthesis of multiple-pinhole camera X-ray photos, for the purpose of S/N increase. The results obtained illustrate new extensions of the basic "holographic Fourier-transform division method" first described by G. W. Stroke and R. H. Zech in 1967, for the first category, and of the method described by G. W. Stroke in 1968, for the second. A review of image deblurring principles and of methods used will be given.
