Abstract
A method, information processing apparatus, and a non-transitory computer-readable storage medium are provided. In the method, a location of an edge of an eye in a first image of a face is determined. An area of the first image based on the determined location is determined. The area of the first image is divided into first and second subareas based on pixel values of the area of the first image. The first subarea includes the pixel values of a first range and the second subarea includes the pixel values of a second range, and an average pixel difference of the first and second ranges is greater than a threshold. The location of the pupil is determined based on a location of one of the first and second subareas when the average pixel difference of the first and second ranges is greater than the threshold.
