Paper Abstract

A multiobject shift invariant pattern recognition system using binary phase-only correlation is presented. The system computes the binary correlation between an input pattern with a generalized set of pattern functions. This technique uses a filter which consists of a set of binary phase-only code division multiplexed reference pattern functions. There are many advantages in binarizing the filter function. Binary spatial light modulators (SLM) have been developed that work well in a binary phase-only mode and can be used to synthesize the spatial filters of this type. Binarization also permits the recording of filters of images with larger samples on currently available binary SLM's that have a limited number of pixels. The functions in the reference set may correspond to either different objects or different variations of the object under study. A computer simulation of the correlator is used to study the performance of the pattern recognition system. The correlation SNR is evaluated as the criterion for the system performance.
