Nonnegative Low Rank Tensor Approximation and its Application to Multi-dimensional Images

no code implementations28 Jul 2020 Tai-Xiang Jiang, Michael K. Ng, Junjun Pan, Guangjing Song

The main aim of this paper is to develop a new algorithm for computing nonnegative low rank tensor approximation for nonnegative tensors that arise in many multi-dimensional imaging applications.

Robust Tensor Completion Using Transformed Tensor SVD

no code implementations2 Jul 2019 Guangjing Song, Michael K. Ng, Xiongjun Zhang

In this paper, we study robust tensor completion by using transformed tensor singular value decomposition (SVD), which employs unitary transform matrices instead of discrete Fourier transform matrix that is used in the traditional tensor SVD.
