[ What is claimed is:] [1.] A method of classifying a pattern, said method comprising the steps of:acquiring a signal, said signal including an input pattern to be classified;sampling the acquired signal to produce an intermediate pattern based on said signal;performing a transform on at least a portion of said intermediate pattern, said transform being from the group consisting of wavelet transforms and wavelet packet transforms, to produce a wavelet transformed pattern;selecting a reduced feature space from the wavelet transformed pattern; andclassifying said input pattern on the basis of said reduced feature space.
