This paper proposes a novel descriptor called Mean-Variance-Median based LBP (MVM-LBP). The Median binary pattern (MBP) calculates the difference between median of all the pixels in a 3 × 3 pixel window and respective eight neighbours is used. The main draw back of MBP is that two different pixel windows can have same MBP code which is not appropriate in face recognition systems. To improve the performance of the system, the proposed descriptor (MVM-LBP) involves more statistics and uses the mean, variance, and median values of all the pixels in a 3 × 3 pixel window to get a more robust feature vector. To check the excellence the of the proposed descriptor, the proposed method is applied on two publicly available facial data sets AT&T, and faces94. The outcomes show that the proposed descriptor gives encouraging results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
