Application of the Walsh Transform in an Integrated Algorithm for the Detection of Interictal Spikes

Abstract

This paper introduces a novel spike detection algorithm based on the use of Walsh Transforms. The algorithm focuses on the assessment of characteristics in the Electroencephalogram (EEG) signal that reveal the presence of a spike feature. The mathematical formulation of the algorithm is introduced and results obtained from the analysis of data from 7 epileptic patients are presented.
