Fast and Efficient Sparse 2D Discrete Fourier Transform using Sparse-Graph Codes
Frank Ong, Sameer Pawar, Kannan Ramchandran
We present a novel algorithm, named the 2D-FFAST, to compute a sparse 2D-Discrete Fourier Transform (2D-DFT) featuring both low sample complexity and low computational complexity.…

Beyond Low Rank + Sparse: Multi-scale Low Rank Matrix Decomposition
Frank Ong, Michael Lustig
We present a natural generalization of the recent low rank + sparse matrix decomposition and consider the decomposition of matrices into components of multiple scales. Such decompo…
