Claim Text:
1. A wrinkle detection apparatus comprising: a memory that stores instructions; and a processor that, when executing the instructions stored in the memory, performs operations comprising: obtaining an image including skin; estimating a plurality of image areas in the image, each of the plurality of image areas belonging to either a first area or a second area other than the first area, the first area extending from a lower eyelid of a left eye to above a left cheek and extending from a lower eyelid of a right eye to above a right cheek; determining first parameter values for each of the estimated image areas belonging to the first area and second parameter values for each of the estimated image areas belonging to the second area, detecting a wrinkle area in the image by calculating first gradient values in the first area by using the Gabor filter adopting the first filter angle and the first filter wavelength, calculating second gradient values in the second area by using the Gabor filter adopting the second filter angle and the second filter wavelength, comparing each of the first gradient values with the first threshold value, and comparing each of the second gradient values with the second threshold value.
