  • Face recognition device and method that update feature amounts at different frequencies based on estimated distance
    Patent number: 9621779
    Abstract: A face recognition device includes: an image capture unit, an area detection unit, a feature amount extraction unit, a distance estimation unit and a feature amount update unit. The image capture unit is configured to capture an image of an object. The area detection unit is configured to detect a given area of the object based on an image obtained as an image capture result of the image capture unit. The feature amount extraction unit is configured to extract a feature amount within the given area detected by the area detection unit. The distance estimation unit is configured to estimate a distance between the image capture unit and the given area. The feature amount update unit is configured to update the feature amount extracted by the feature amount extraction unit based on the distance estimated by the distance estimation unit.
