Edge detector tolerant to object defocusing

Different methods for edge extraction have been studied in the past years. In a recent paper we have presented a rotation-invariant edge extractor based on a spiral phase filter placed in the frequency plane of a convergent correlator. In this architecture, the axial position of the output plane str...
