A rule-based optical symbolic and inference processor concept using a relational graph is described. The architecture and its design are discussed and detailed for one example. The system uses a Fourier/polar/Mellin/Fourier transform representation space and the case studies addressed involve aircraft identification and classification. However, the basic rule-based optical-inference relational graph processor concept and architecture are quite general purpose.
