Gegenbauer Transforms via the Radon Transform [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 1979
Use is made of the Radon transform on even dimensional spaces and Gegenbauer functions of the second kind to obtain a general Gegenbauer transform pair. In the two-dimensional limit the pair reduces to a Chebyshev transform pair.

Inversion Formula for a Radon-Type Transform Arising in Photoacoustic Tomography with Circular Integrating Detectors

open access: yesAdvances in Mathematical Physics, 2018
This paper is devoted to a Radon-type transform arising in a version of Photoacoustic Tomography that uses integrating circular detectors. The Radon-type transform that arises can be decomposed into the known Radon-type transforms: the spherical Radon ...

Kernel-based Image Reconstruction from Scattered Radon Data [PDF]

open access: yes, 2016
Computerized tomography requires suitable numerical methods for the approximation of a bivariate function f from a finite set of discrete Radon data, each of whose data samples represents one line integral of f .

Road Detection by Using a Generalized Hough Transform

open access: yesRemote Sensing, 2017
Road detection plays key roles for remote sensing image analytics. Hough transform (HT) is one very typical method for road detection, especially for straight line road detection.

Inverse of Affine Radon Transform for Light Field Reconstruction From Focal Stack

open access: yesIEEE Access, 2018
The light field can be applied to computational imaging methods, such as digital refocusing, depth reconstruction, and all-in-focus imaging. In this paper, the affine Radon transform of generating the focal stack by the light field is proposed.

Inversion formulas for quarter-spherical Radon transforms

open access: yesAIMS Mathematics, 2023
The applications of spherical Radon transforms include synthetic aperture radar, sonar tomography, and medical imaging modalities. A spherical Radon transform maps a function to its integrals over a family of spheres.

Reconstruction from Radon projections and orthogonal expansion on a ball

open access: yes, 2007
The relation between Radon transform and orthogonal expansions of a function on the unit ball in $\RR^d$ is exploited. A compact formula for the partial sums of the expansion is given in terms of the Radon transform, which leads to algorithms for image ...

Some uniqueness theorems for a conical Radon transform

open access: yesJournal of Physics Communications, 2023
The conical Radon transform, which assigns to a given function f on ${{\mathbb{R}}}^{3}$ its integrals over conical surfaces, arises in several imaging techniques, e.g. in astronomy and homeland security, especially when the so-called Compton cameras are
