Apparatus and method for face recognition and computer program

A face recognition method for previously registering a face image of a person, receiving a moving image in which face identification is intended to be performed, and performing face recognition in the received moving image, the method comprising:

• registering the face of a person as an image in a face registration unit;
• detecting an image of the face in a frame of an input moving image;
• tracking the detected image of the face in frames of the input moving image;
• comparing the detected image of the face, which is being tracked in the tracking, with the registered face registered in the face registration unit to identify the detected image of the face;
• and
• updating, using a processor, the registered face, registered in the face registration unit, of the person whose face has been identified in the comparing to a present detected image of the face of the person only once each predetermined frame period of the moving image to stabilize a result of face identification, the predetermined frame period being equal to five frames.

A non-transitory computer readable medium encoded with a computer program described in computer-readable form so as to allow a computer to execute a method for previously registering a face image of a person, receiving a moving image in which face identification is intended to be performed, and performing face recognition in the received moving image, the method comprising:

• registering the face of a person as an image in a face registration unit;
• detecting an image of the face in a frame of an input moving image;
• tracking the detected image of the face in frames of the input moving image;
• comparing the detected image of the face, which is being tracked in the tracking, with the registered face registered in the face registration unit to identify the detected image of the face;
• and
• updating, using a processor, the registered face, registered in the face registration unit, of the person whose face has been identified in the comparing to a present detected image of the face of the person only once each predetermined frame period of the moving image to stabilize a result of face identification, the predetermined frame period being equal to five frames.

A face recognition apparatus for previously registering a face image of a person, receiving a moving image in which face identification is intended to be performed, and performing face recognition in the received moving image, the apparatus comprising:

• a face registration unit that registers the face of a person as an image;
• a face detection unit that detects an image of the face in a frame of an input moving image;
• a face tracking unit that tracks the detected image of the face in frames of the input moving image;
• a face identification unit that compares the detected image of the face, which is being tracked by the face tracking unit, with the registered face registered in the face registration unit to identify the image of the face;
• and
• a stabilization unit that stabilizes a result of face identification by the face identification unit, the stabilization unit updating the registered face, registered in the face registration unit, of the person whose face has been identified by the face identification unit to a present detected image of the face of the person only once each predetermined frame period of the moving image, the predetermined frame period being equal to five frames.
