Face recognition has been actively studied over the past decade and continues to be a big research challenge. Just recently, researchers have begun to investigate face recognition under unconstrained conditions. Unconstrained Face Recognition provides a cmprehensive review of this biometric, especially face recognition from video, assembling a collection of novel approaches that are able to recognize human faces under various unconstrained situations. The underlying basis of these approaches is that, unlie conventional face recognition algorithms, they exploit the inherent characteristics of the unconstrained situation and thus improve the recognition performance when compared with conventional algorithms. Unconstrained Face Recognition is structured to met the needs of a professional audience of researchers and practitioners in industry. This volume is also suitable for advanced-level students in computer science. Это и многое другое вы найдете в книге Unconstrained Face Recognition (International Series on Biometrics) (Shaohua Kevin Zhou, Rama Chellappa, Wenyi Zhao)
