Disclosed are novel techniques for high-precision sex 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 the estimated age of the subject is calculated by applying the calculated spatial frequency intensities obtained from the facial image data.

Age estimation method and sex determination method

On the methods of creating corneocyte specimen for providing useful information for appropriate selection of cosmetic products or assessment of the skin condition, it is intended to provide a method of indicating an unstained image of corneocytes or the like in an observable pseudocolor in a method of creating corneocyte specimen, without resorting to staining the corneocyte specimen. The state of corneocytes of skin is input into a computer as an enlarged image by using, for example, a digital microscope. Then, the RGB values of the individual pixels in the image are converted with the use of a conversion system such as a conversion formula, a conversion table or a conversion chart and an image is indicated in a pseudocolor by using the individual RGB values converted.
