Two Approaches of Implementing Fractional Correlation Operation

Abstract

This paper concerns mainly about two approaches to implement the anamorphic fractional correlation operation. Firstly, the definition of anamorphic fractional correlation is introduced. Secondly, an optical approach of implementing the correlation operation is presented. Lastly, since the optical implementation is somewhat troublesome, we will show how to exploit the anamorphic fractional correlation by computer-generated holography.
