Multiresolutional filtering for evoked potential estimation using wavelet transform coefficients
Yeganeh Payam, M. Mohammad, Ramy Amin Kamel Ali · 2001
Summary form only given. We would like to propose a method for estimation of evoked potentials (EP) using Multiresolutional filters based on the wavelet transform (WT) coefficients. These filters are simply implemented by wavelet transforming of the recorded signal (EP+Noise), selection of some critical coefficients, applying a noise reduction method and inverse wavelet transforming the result coefficients. In this paper we use above procedure for estimation of Brainstem Auditory Response (ABR) and Visual Evoked Potentials (VEP).
