Recovering Missing Slices of the Discrete Fourier Transform using Ghosts
Shekhar Chandra, Imants Svalbe, Jeanpierre Guedon +2
The Discrete Fourier Transform (DFT) underpins the solution to many inverse problems commonly possessing missing or un-measured frequency information. This incomplete coverage of F…
Fast Mojette Transform for Discrete Tomography
Shekhar S. Chandra, Nicolas Normand, Andrew Kingston +2
A new algorithm for reconstructing a two dimensional object from a set of one dimensional projected views is presented that is both computationally exact and experimentally practic…
Fast Digital Convolutions using Bit-Shifts
Shekhar S. Chandra
An exact, one-to-one transform is presented that not only allows digital circular convolutions, but is free from multiplications and quantisation errors for transform lengths of ar…
