Singular Value Decomposition Approximation via Kronecker Summations for Imaging Applications
Clarissa Garvey, Chang Meng, James G. Nagy
In this paper we propose an approach to approximate a truncated singular value decomposition of a large structured matrix. By first decomposing the matrix into a sum of Kronecker p…
