Abstract

A method of identifying non-conforming groups of items within a package, the package containing a plurality of groups of items, comprises obtaining a reference signal corresponding to a package containing conforming groups of items, obtaining a signal corresponding to each of the plurality of groups of items in the package, comparing the signal corresponding to each of the plurality of groups of items with the reference signal, determining whether any of the plurality of groups of items is nonconforming, and segregating the package based on whether the package contains a nonconforming group of items.
