Iterative reconstruction of images from Fourier-transform phase using moments

Not Accessible

Your library or personal account may give you access

Abstract

Spatial information in Fourier-transform phase and magnitude has been investigated. The first moments of an image have been deduced from the given phase for use as space-domain constraints in the iterative technique. An algorithm has been developed by replacing generally used truncation operations with the moment constraints. Experimental results employing the new algorithm are presented.
