Paper Abstract

Deblurring images affected by severe focus defeat gives often poor results. A coherent optical method, the joint Fourier transform correlation, is suggested for the recognition of defocused images. Basing on the symmetry of the crosscorrelation function between an out-of-focus and the in-focus image, the recognition may be attempted simply correlating the unknown out-of-focus image with a set of reference in-focus images.
