Paper Abstract

Synthesis of gray level computer generated holograms allows to increase the information storage capability of complex filters. In this work we study the capability of gray level filters to perform multichannel correlation. To this end a composed synthetic discriminant function filter is employed to implement an object classification by means of a binary code.
