“…The matrix SVD factorization (1.1) was extended to third order tensors as T-SVD factorization by Kilmer and Martin [4,5]. The T-SVD factorization has been found wide applications in engineering and tensor computation [1,3,6,7,8,10,11,13,14,15,16,17,18,19,21,20,22,23]. In T-SVD factorization, an m × n × p third order real tensor A is decomposed to the tensor product of an m × m × p orthogonal tensor U, an m × n × p real f-diagonal tensor S, and an n × n × p orthogonal tensor V:…”
