Abstract

A hyperspace description of a matched spatial filter (MSF) correlator is advanced and used to develop a new MSF that is a synthetic discriminant function (SDF). The use of this filter to recognize objects independent of their aspect is described. Terminal homing recognition of tanks from IR imagery is taken as a case study. Bandpass filtering and a new maximum common information filter synthesis concept and issues such as filter energy are described and used to improve the system's intra-class pattern recognition ability and to overcome the intensity differences present in IR imagery. Experimental verification is also included.
