Title:
PEAK DETECTION METHOD AND DATA PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/208304
Kind Code:
A1
Abstract:
A peak detection method for detecting a peak from graph data expressing the variation of measurement values for a measurement variable, wherein the method comprises a wavelet transformation step (S2) for carrying out wavelet transformation on the data using a mother wavelet having only one maximum value and thereby determining an evaluation function having the scale and translation of the mother wavelet as parameters and peak candidate information acquisition steps (S3-S5) for determining a peak candidate position in the data on the basis of the translation for the part of the evaluation function having the maximum value and determining the width of the peak candidate on the basis of the scale corresponding to the peak candidate. Carrying out wavelet transformation makes it possible to detect a peak candidate regardless of peak strength, and the like, and it is possible to determine the width of the peak candidate, which serves as an index for determining whether the peak candidate is a true peak.
