Recognition and Reconstruction of Late Auditory Evoked Potentials Using Wavelet Analysis

In this paper we introduce a recognition and reconstruction method for late auditory evoked potentials (AEPs) using wavelet analysis. AEPs are part of the Electroencephalo-gram (EEG) in reaction to acoustic stimuli and are used for diagnostic purposes. The decomposition of the EEG measurement data into subbands can yield a parameteriza-tion of the AEP using a small number of signiicant coee-cients, which can be determined by surveying distributions of the transform coeecients. This method is more reliable than traditional means, and additionally ooers the possibility of reconstructing potential AEPs by performing an inverse transform on signiicant coeecients.
