Signal Decomposition Techniques for Railroad Track Safety and Ride Quality Features Extraction: A Multicriteria Selection Framework

Abstract

AbstractThis paper investigates the feature extraction effectiveness of three signal decomposition techniques, short-time Fourier transform (STFT), Hilbert Huang transform (HHT), and wavelet transform (WT), for analyzing railroad track geometry data. ...Practical ApplicationsThis study evaluates and compares the performance of three signal decomposition techniques used to analyze railroad track geometry data for track conditions assessment. Analysis of track geometry data to extract features relevant to ...
