“…This information may sometimes be an average intensity value, texture information, variance, and edge information in a different orientation. Also, many previous studies ( Karanwal & Diwaker, 2021 ; Guo et al, 2017 ; Wang et al, 2015 ; Suk & Flusser, 2009 ; Ojala, Pietikäinen & Harwood, 1996 ; Karami, Prasad & Shehata, 2017 ; Ahonen, Hadid & Pietikäinen, 2004 ; Hadid, 2008 ; Huijsmans & Sebe, 2003 ; Grangier & Bengio, 2008 ; Ali, Georgsson & Hellstrom, 2008 ; Nanni & Lumini, 2008 ; Mäenpää, Viertola & Pietikäinen, 2003 ; Turtinen, 2006 ; Heikkila & Pietikainen, 2006 ; Kellokumpu, Zhao & Pietikäinen, 2008 ; Oliver et al, 2007 ; Kluckner et al, 2007 ; Fisher, Stein & Fisher, 2005 ; Sharma, Jain & Khushboo, 2019 ) proved the high efficiency of the LBP as a local feature descriptor for the images. From the above results, we can observe that our proposed face recognition system has high accuracy and less recognition time, where the size of the extracted feature vector is relatively small compared with the other recently published methods ( Sajjad et al, 2020 ; Karami, Prasad & Shehata, 2017 ).…”
