Retina-like Adaptive Thresholding in a Nonlinear Joint Transform Correlator

Not Accessible

Your library or personal account may give you access

Abstract

Joint transform correlators, now made practical by the availability of many electrically- and optically- addressed spatial light modulators (SLM) and convenient coherent light sources, have been shown to be effective at both optical pattern recognition (OPR) [1] and tracking [2].
