However, by using the relative variation of the pixel intensity as shown in (7)–(11) as the feature of the face image, improved interest operator 1 is able to from improved interest operator 1, the second improvement operator takes as the feature of an image block the result of the conventional interest operator divided by the sum of the mean of the pixel Khor, Woo, & Dlay, 2006; Nhat & Lee, 2005; Sanguansat, Asdornwised, Jitapunkul, & Marukatat, 2006; Wang, Wang, Zhang, & Feng,	./cache/work_3vtrulz3czgv7pbhfl7yw5lxem.pdf	./txt/work_3vtrulz3czgv7pbhfl7yw5lxem.txt
