Analysis of EEG and MEG Signals with Matching Pursuit

Introduction: A wide spectrum of methods has been used for analysis of biomedical signals. A relatively new and promising approach to signal analysis is matching pursuit (MP). The main advantage of the MP algorithm is its ability to create a concise description of an analyzed signal with a relatively small number of components localized in the time-frequency space with maximal possible, adaptive resolution. We applied MP to real MEG and EEG signals in order to present its possible applications. Methods: MP creates signal approximations based on a linear combination of a small number of vectors (atoms) chosen fro…
