<p><P>PROBLEM TO BE SOLVED: To accurately extract a non-linear structure included in time series data signals having irregular fluctuation with respect to a processing method of time series data, a processing program of time series data and a processing system of time series data. <P>SOLUTION: A plurality of first featured points featuring the variation of time series data signals having irregular fluctuation are extracted from those time series data signals (A20), and second feature points are set in the neighborhood of the plurality of first feature points (A30). Also, the first state of fluctuation to be acquired from the first feature points and the second state of fluctuation to be acquired from the second feature points are analyzed (A40, A50). Furthermore, the template of a non-linear structure is set based on the first state of fluctuation (A60). The feature points related with either the first state or the second state having the non-linear structure closer to the template are selected (A70). <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
