Abstract:
1. A method for decomposing an input signal into a baseline signal and a residual output signal, comprising the steps of: (a) receiving an input signal into a processor; (b) determining a monotonic residual segment with strictly negative minimum and strictly positive maximum and a baseline segment wherein said segments are defined on a time interval, the 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 the monotonic residual segments; and (c) producing a baseline output signal and a residual output signal, wherein the baseline output signal is obtained from the baseline segment and the residual output signal is obtained from the monotonic residual segment as determined in step (b), such that the sum of the baseline and residual output signals is equal to the input signal thereby forming a decomposition of the input signal.
