Paper: Generation of Facial Expression Map using Supervised and Unsupervised Learning

Recently, studies of human face recognition have been conducted vigorously (Fasel &
Luettin, 2003; Yang et al., 2002; Pantic & Rothkrantz, 2000a; Zhao et al., 2000; Hasegawa et
al., 1997; Akamatsu, 1997). Such studies are aimed at the implementation of an intelligent
man-machine interface. Especially, studies of facial expression recognition for human-
machine emotional communication are attracting attention (Fasel & Luettin, 2003; Pantic &
Rothkrantz, 2000a; Tian et al., 2001; Pantic & Rothkrantz, 2000b; Lyons et al., 1999; Lyons et
al., 1998; Zhang et al., 1998).
