AGE ESTIMATION METHOD AND SEX DETERMINATION METHODABSTRACTDisclosed are novel techniques for high-precision sex5 determination and age estimation using facial images. The disclosed age estimation method includes: a step in which facial image data of a subject is acquired a step in which spatial frequency intensities are calculated from the acquired facial image data and a step in which the10 estimated age of the subject is calculated by applying the calculated spatial frequency intensities obtained from the facial image data.Figure 6
