Patent number: 7715659Abstract: An apparatus for and method of performing a most informative feature extraction (MIFE) method in which a facial image is separated into sub-regions, and each sub-region makes individual contribution for performing facial recognition. Specifically, each sub-region is subjected to a sub-region based adaptive gamma (SadaGamma) correction or sub-region based histogram equalization (SHE) in order to account for different illuminations and expressions. A set of reference images is also divided into sub-regions and subjected to the SadaGamma correction or SHE. A comparison is made between the each corrected sub-region and each corresponding sub-region of the reference images. Based upon the comparisons made individually for the sub-regions of the facial image, one of the stored reference images having the greatest correspondence is chosen.Type: GrantFiled: July 19, 2004Date of Patent: May 11, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Jiali Zhao, Dejun Wang, Haibing Ren, Seokcheol Kee
