Abstract:In this paper, an active vision system used for real time facial features tracking is presented, where a human head region is searched using a stereo camera. This region is divided such that a person's nose will be searched in a smaller spatial domain. The 2D coordinates of the nose are determined based on a Haar classifier and colour segmentation. Its 3D coordinates, computed via the constraints of the epipolar geometry, represent a reference signal used within a control system for controling the stereo camer… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
