Fps-Sft: A Multi-Dimensional Sparse Fourier Transform Based on the Fourier Projection-Slice Theorem
ICASSP 2018accepted
We propose a multidimensional sparse Fourier transform inspired by the idea of the Fourier projection-slice theorem, called FPS-SFT. FPS-SFT extracts samples along lines (1-dimensional slices from a multidimensional data cube), which are parameterized by random slopes and offsets. The discrete Fouri…
