Abstract: Disclosed herein are an apparatus and method for registering face poses for face recognition. The apparatus includes a face detection unit for detecting the face of a user from an image including the face of the user; a pose recognition unit for recognizing the face pose of the face of the user based on the degree of rotation of the face of the user; a registration interface unit for providing an interface for showing information about whether the face poses of the face of the user are registered; and a face registration unit for registering the face pose of the face of the user when the face pose of the face of the user is recognized as an unregistered face pose based on the interface.

Abstract: Disclosed herein are a facial recognition method and apparatus based on masking. The facial recognition method based on masking includes performing detection and normalization of a face area including five landmarks in an input image, separating a face portion other than a portion covered by an obstacle in the detected face area, generating a mask corresponding to the separated face portion when there is a portion covered by an obstacle in the separated face portion, applying the mask to an image in a face image registration database and extracting a feature of a masking region, and determining whether it is an identical person based on the extracted feature value.

Abstract: Disclosed herein is a user authentication apparatus that captures images of the back and/or the palm of a hand using both a mobile camera, such as a smart phone or a smart pad, and a high-resolution stationary camera embedded in a PC, extracts various types of biometric information from the captured images, registers the extracted biometric information, and authenticates a new image when the new image is input. The user authentication apparatus includes a hand area detection unit for detecting a hand area from an input hand image, a hand area normalization unit for binarizing the detected hand area and normalizing the binarized hand area, a hand biometric information extraction unit for extracting unique hand biometric information from the normalized hand area, and a hand biometric information registration and authentication unit for registering the hand biometric information and authenticating the corresponding user based on the hand biometric information.

Abstract: A face recognition technology using physiognomic feature information, which can improve the accuracy of face recognition. For this, the face recognition method using physiognomic feature information includes defining standard physiognomic types for respective facial elements, capturing a facial image of a user, detecting information about facial elements from the facial image, and calculating similarity scores relative to the standard physiognomic types for respective facial elements of the user based on the facial element information.
