Abstract
In Pattern Recognition problems, the input scene of an optical system setup could present some optical or physical degradation like as defocusing. In that case the pattern recognition process may be affected, depending of the kind of filter that is used [1]. In general, both the correlation and the crosscorrelation peaks decrease when the amount of defocusing increases, with the result that the discrimination capability (DC) decreases as blurring increases.
