METHOD FOR EXTRACTING NON-PERIODIC PATTERNED MOTIFS BY PERIODIC PATTERNS, AND DEVICE USING THE METHOD

摘要

The present invention relates to a method for extracting information of interest from a measurement signal comprising a periodic perturbation pattern, which comprises steps (i) of generating a filtering function representative of the frequency components of the signal pattern. disruption, by implementing an analysis of an amplitude spectrum of the measurement signal based on morphological criteria, (ii) applying said filtering function to the measurement signal so as to generate a disturbance signal constituted essentially the disturbance pattern; and (iii) calculating a filtered signal by making a difference between the measurement signal and the disturbance signal. The invention also relates to a device implementing the method.
