Facial expression recognition using emotion avatar image
Face and Gesture 2011
Existing facial expression recognition techniques analyze the spatial and temporal information for every single frame in a human emotion video. On the contrary, we create the Emotion Avatar Image (EAI) as a single good representation for each video or image sequence for emotion recognition. In this paper, we adopt the recently introduced SIFT flow algorithm to register every frame with respect to an Avatar reference face model. Then, an iterative algorithm is used not only to superresolve thedoi:10.1109/fg.2011.5771364 dblp:conf/fgr/YangB11 fatcat:bqqkf6xserd37c52jgeirdwwl4
