摘要

The image for the face candidate region is obtained, extraction conditions are determined for extracting the eye and the mouth pixels from the face candidate region based on the size of the face candidate region. The eye pixels and the mouth pixels are then extracted from the face candidate region based on the determined extraction conditions, and then the area ratio of the eyes and the area ratio of mouth are calculated for the face candidate region based on the eye pixels and the mouth pixels. Next the area ratio for the eyes and mouth is input into the neural network and a determinations is made as to whether the face candidate region is the face of a person using the neural network.
