Do facial expressions develop before birth? [PDF]
, 2011 Background: Fetal facial development is essential not only for postnatal bonding between parents and child, but also theoretically for the study of the origins of affect. However, how such movements become coordinated is poorly understood. 4-D ultrasound

Parametric Representations of Facial Expressions on PDE-Based Surfaces [PDF]
, 2008 YesParameterisation of facial expressions on PDE surface representations of human faces are presented in this work. Taking advantage of the boundary-value approach inherent to Bloor-Wilson PDE method, facial expressions are achieved by manipulating the ...

Recognition and Intensity Estimation of Facial Expression Using Ensemble Classifiers [PDF]
International Journal of Networked and Distributed Computing (IJNDC), 2016 Facial expression recognition (FER) has been widely studied since it can be used for various applications. However, most of FER techniques focus on discriminating typical facial expressions such as six basic facial expressions.
