Abstract:
1. A method for decomposing an input signal into a baseline signal and a residual signal or determining time-frequency-energy information of an input signal at a selected time, the method comprising the steps of: (a) selecting an input signal comprising data or information from geophysical signals, seismic signals, sea surface temperature signals, radiometer signals, environmental signals, biologic signals, telecommunication signals, acoustic signals, crystallographic signals, spectroscopic signals, electrical signals, magnetic signals, trajectory signals, structural vibration signals, structural resonance signals, electrical circuit signals, and financial market signals; (b) receiving the selected input signal into a processor; (c) determining a monotonic residual segment from the selected input signal with strictly negative minimum and strictly positive maximum and a baseline segment wherein said segments are defined on an interval between two successive extrema of the selected input signal and wherein the selected input signal on that interval is the sum of the baseline and residual segments; (d) producing a baseline output signal from the selected input signal and a residual output signal from the selected input signal wherein the baseline signal is obtained from the baseline segment and the residual segment is obtained from the residual segment as determined in step (c), such that the sum of the baseline and residual signals is equal to the selected input signal thereby forming a decomposition of the selected input signal; and (e) determining from the baseline output signal and the residual output signal, time-frequency-energy information at a selected time.
