Wavelet analysis of one or more acoustic signals to identify one or more anomalies in an object

摘要

In one embodiment, a method for wavelet analysis of one or more acoustic signals to identify one or more anomalies in an object includes receiving an acoustic signal from an acoustic scan of an object and calculating a wavelet power spectrum of the acoustic signal. The method also includes accessing a library of one or more reference wavelet power spectra that each correspond to one or more objects that comprise one or more known anomalies and comparing the wavelet power spectrum with one or more reference wavelet power spectra. If the wavelet power spectrum from the acoustic scan corresponds to one or more reference wavelet power spectra, analysis results are communicated indicating that the object under analysis comprises one or more particular known anomalies corresponding to the one or more reference wavelet power spectra that correspond to the wavelet power spectrum. If the wavelet power spectrum does not correspond to one or more reference wavelet power spectra, analysis results are communicated indicating that the object under analysis lacks the one or more known anomalies that the one or more reference wavelet power spectra in the library correspond to.
