Signal processing for event detection
L. Ahlbom, A. Forsen, L. Zetterberg · 2005
A recursively updated lattice filter has been used for detection of non-stationarities in stochastic processes. Detection of these may be based either on the residual or the filtercoefficients. A decision variable defined from the filter-coefficients has been found promising in application of the algorithm to seismic signals and to electroencephalograms.
