Paper Abstract

We design an incoherent correlator based on the shadow casting principle, including a bipolar representation of correlation filters. This correlator is totally new to our knowledge, and is furthermore very simple and low cost, although it can not handle large resolution images. The bipolar technique allows us to represent any linear filter in the correlator. We demonstrate experimentally its efficiency in the case of optimal trade-off filters.
