Surface classification by an optoelectronic implementation of the Karhunen–Loève expansion

Abstract

An optical–digital approach to the classification of rough surfaces that uses a Fourier-transform feature space is described. The sampling of the two-dimensional Fourier spectrum is achieved with a charge-coupled device detector array, which has a polar-sampling geometry and reduces an infinitely dimensioned spectrum image into a set of 72 measurements. To discriminate among three plastic samples in this reduced subspace, we use the Karhunen–Loève transformation. Then the classification procedure automatically selects the best subspace from the Karhunen–Loève vectors.
