INTRINSIC TIMESCALE DECOMPOSITION, FILTERING, AND AUTOMATED ANALYSIS OF SIGNALS OF ARBITRARY ORIGIN OR TIMESCALE

摘要

A method, computer program, and system for intrinsic timescale decomposition, filtering, and automated analysis of signals of arbitrary origin or timescale including receiving an input signal into a processor, determining a baseline segment and a monotonic residual segment with strictly negative minimum and strictly positive maximum wherein said segments are defined on a time interval comprising the interval between two successive extrema of the input signal and wherein the input signal on that interval is the sum of the baseline and residual segments, and producing a baseline output signal and a residual output signal wherein the baseline signal is obtained from the baseline segment and the residual signal is obtained from the residual segment such that the sum of the baseline and residual signals is equal to the input signal thereby forming a decomposition of the input signal.
