  abstract = {To be effective in the human world robots must respond to human emotional
	states. This paper focuses on the recognition of the six universal
	human facial expressions. In the last decade there has been successful
	research on facial expression recognition ({FER)} in controlled conditions
	suitable for human-computer interaction. However the human-robot
	scenario presents additional challenges including a lack of control
	over lighting conditions and over the relative poses and separation
	of the robot and human, the inherent mobility of robots, and stricter
	real time computational requirements dictated by the need for robots
	to respond in a timely fashion. Our approach imposes lower computational
	requirements by specifically adapting model-based techniques to the
	{FER} scenario. It contains adaptive skin color extraction, localization
	of the entire face and facial components, and specifically learned
	objective functions for fitting a deformable face model. Experimental
	evaluation reports a recognition rate of 70\% on the Cohn-Kanade
	facial expression database, and 67\% in a robot scenario, which compare
	well to other {FER} systems.},
