Publication number: 20110141257Abstract: A facial image registration apparatus and method are provided for registering a plurality of facial images to be used for face recognition. A plurality of facial images are detected and sorted from a plurality of captured images input from a camera unit at the request of a user. A face feature value is calculated for each of the facial images. The face feature value is a score that is applied according to face features of each of the facial images. Facial images selected according to the calculated face feature values are registered as target facial images to be used for face recognition. As such, various facial images may be registered at a user's single request, thus improving a face recognition rate.Type: ApplicationFiled: December 15, 2010Publication date: June 16, 2011Applicant: Samsung Electronics Co., Ltd.Inventors: Yoon-Choon Hwang, Sung-Dae Cho, Byung-Jun Son, Tae-Hwa Hong, Chung-Hoon Kim, Nitin Singhal
