Sparse Representation Based Face Recognition Algorithm
Jingyu Yang · 2010
We analyzed the mathematic essence of sparse representation,sparse regularized signal decomposition.Stu-died a sparse representation algorithm of orthogonal matching pursuit.Using the matrix Cholesky decomposition,we rea-lized the OMP algorithm a fast version.We cast the recognition problem as one of classifying among multiple linear regression models and developed a new framework from sparse signal representation.We viewed a test sample as the linearcombination of training samples.We conducted experiments on face recognition to verify the efficacy of the proposed algorithm.
