Abstract

A new feature representation approach was proposed [1]for those cases when one or multi-dimensional Fourier trans-forms (FT) are used for pattern recognition. This approachconsists of using simultaneously two new recognition fea-tures: real and imaginary components of the FT. It wasshown [1,2] that this approach is more generic than powerspectral density (PSD) and phase spectrum approaches andprovides better recognition e5ectiveness than the PSD ap-proach, which is a particular case of the proposed approach.This is in contrast to most recognition applications, wherePSD and phase spectrum are used.
