A classification apparatus includes: a spectrogram generation unit that generates a spectrogram of a time variation signal of a classification object by processing the time variation signal of the classification object obtained by a sensor; a two-dimensional Fourier transform calculation unit that calculates a two-dimensional Fourier transform of the generated spectrogram; a similarity calculation unit that calculates a similarity between an template image and an image of the obtained two-dimensional Fourier transform, for each template image corresponding to each phenomenon stored in the template image memorizing unit; and a determination unit that determines whether the time variation signal of the classification object conforms to any of one or more phenomena, on the basis of the calculated similarity. |
