Ching-Hui Chen; Rama Chellappa    Department of Electrical and Computer Engineering, University of Maryland, College Park, MD, United States

Abstract

Face recognition in outdoor environment is a challenging task due to illumination changes, pose variations, and occlusions. In this chapter, we discuss several techniques for continuous tracking of faces acquired by an outdoor camera network as well as a face matching algorithm. Active camera networks are capable of reconfiguring the camera parameters to collaboratively capture the close-up views of face images. Robust face recognition methods can utilize compact representations extracted from multi-view videos. In the meantime, ...
