Using a sparse-constrained non-negative matrix factorization ( NMF) algorithm , a facial aging simulation method based on an improved prototype was first proposed and then applied to age-span face recognition to add virtual sam- ples and heighten the recognition rate . Experimental results show that the age span indeed has a great effect on face recognition; the NMF algorithm has stronger feature extraction ability when the coefficient matrix is sparsely con- strained . Furthermore ...
