Abstract
The present invention relates to a method and apparatus for pain evaluation based on a PPG-based spectrogram and a CNN. The method for pain evaluation based on a PPG-based spectrogram and a CNN, according to an embodiment of the present invention, may comprise the steps of: (a) acquiring a photoplethysmographic (PPG) signal of a user; (b) generating a spectrogram of the PPG signal from the acquired PPG signal; and (c) evaluating the user's pain by using the spectrogram of the PPG signal.
