Wagner, Andrew (2012-02-06)Many classic and contemporary face recognition algorithms work well on public data sets, but degrade sharply when they are used in a real recognition system. A major cause of this is the difficulty of simultaneously handling ...
Yang, Allen Y.; Rao, Shankar; Wagner, Andrew; Ma, Yi; Fossum, Robert M. (Coordinated Science Laboratory, University of Illinois at Urbana-Champaign, 2005-07)This paper develops a new mathematical framework for studying the subspace-segmentation problem. We examine some important algebraic properties of subspace arrangements that are closely related to the subspace-segmentation ...
Wagner, Andrew; Shia, Victor; Yang, Allen; Murphy, Mark; Ma, Yi (Coordinated Science Laboratory, University of Illinois at Urbana-Champaign, 2011-06)Recently a family of promising face recognition algorithms based on sparse representation and `1-minimization (`1-min) have been developed. These algorithms have not yet seen commercial application, largely due to higher ...
