ABSTRACT

In this paper, a new algorithm of image reconstruction from the phase of its Fourier transform is presented. It uses the eigenfilter method to approximate a given phase response in the least square sense. This method has proved its efficiency as the iterative methods. An example will be given to show the importance of this algorithm and the high image reconstruction quality.
