Document Type and Number:
WIPO Patent Application WO/2021/024905
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an image processing device capable of stably performing a face orientation estimation process for a specific individual in real time with high accuracy. The image processing device, which processes an image input from an imaging unit, comprises: a facial feature quantity storage unit which stores, as learned facial feature quantities, a facial feature quantity of a specific individual and a normal facial feature quantity; a face detection unit which detects a face area while extracting a facial feature quantity from the image; a specific individual determination unit which determines whether or not the face in the face area is the face of the specific individual, by using the detected feature quantity of the face area and the facial feature quantity of the specific individual; a first face image processing unit which performs a face image process for the specific individual, when it is determined that the face in the face area is the face of the specific individual; and a second face image processing unit which performs a normal face image process, when it is determined that the face in the face area is not the face of the specific individual, wherein the first face image processing unit includes a specific individual face orientation estimation unit.
