Injectivity and Stability for a Generic Class of Generalized Radon Transforms. [PDF]

open access: yesJ Geom Anal, 2017
Let (M, g) be an analytic, compact, Riemannian manifold with boundary, of dimension n ≥ 2 . We study a class of generalized Radon transforms, integrating over a family of hypersurfaces embedded in M, satisfying the Bolker condition (in: Quinto ...

Quantum Radon Transforms and Their Applications

open access: yesIEEE Transactions on Quantum Engineering, 2022
This article extends the Radon transform, a classical image-processing tool for fast tomography and denoising, to the quantum computing platform. A new kind of periodic discrete Radon transform (PDRT), called the quantum periodic discrete Radon transform

Central and Periodic Multi-Scale Discrete Radon Transforms

open access: yesApplied Sciences, 2021
The multi-scale discrete Radon transform (DRT) calculates, with linearithmic complexity, the summation of pixels, through a set of discrete lines, covering all possible slopes and intercepts in an image, exclusively with integer arithmetic operations. An

A two cones support theorem [PDF]

open access: yesOpuscula Mathematica, 2016
We show that if the Radon transform of a distribution \(f\) vanishes outside of an acute cone \(C_{0}\), the support of the distribution is contained in the union of \(C_{0}\) and another acute cone \(C_{1}\), the cones are in a suitable position, and ...
