A new shape descriptor defined on the Radon transform
Computer Vision and Image Understanding, 2006 International audienceThis paper presents a novel approach to identify complex shapes based on the Radon transform. We propose an adaptation of Radon transform called $\mathcal R$-transform which is invariant to common geometrical transformations ...

The Exponential Radon Transform
SIAM Journal on Applied Mathematics, 1980The exponential Radon transform, a generalization of the Radon transform, is defined and is studied as a mapping of function spaces. An inversion formula is derived. The exponential Radon transform is represented in terms of Fourier transforms of its domain and range, and this leads to a characterization of the range of the transform.The exponential ...

A new algorithm is presented whereby the Radon transform may be computed in a time commensurate with real-time computer vision applications. The computation and storage requirments are optimized using the four-fold symmetry of the image plane and the properties of the transform.

The polynomial discrete Radon transform
Signal, Image and Video Processing, 2014This paper presents a new approach called polynomial discrete Radon transform (PDRT), regarded as a generalization of the classical finite discrete Radon transform. Specifically, the PDRT transforms an image into Radon space by summing the pixels according to polynomial curves. The PDRT can be applied on square

The interior Radon transform arises from a limited data problem in computerized tomography when only rays traveling through a specified region of interest are measured. This problem occurs due to technical restrictions of the sampling apparatus or in an endeavor to reduce the \(X\)-ray dose.

On the Radon Transform and Linear Transformations of Images
Proceedings of the 2019 2nd International Conference on Digital Medicine and Image Processing, 2019We present a novel original method for estimating and recovering a general geometric transformation which is applied to an image. Our main tool is the Radon Transform; we develop analysis to address the behavior of this transform under a Linear Transformation in terms of the singular value decomposition of the Transformation's matrix.

A Generalized Radon Transform on the Plane
Constructive Approximation, 2010The authors define a new generalized Radon transform \(R_{\alpha,\beta}\) on the plane for functions even on each variable. Such \(R_{\alpha,\beta}\) has natural connections with the bivariate Hankel transform, the generalized biaxially symmetric potential operator \(\Delta_{\alpha\beta}\), and the Jacobi polynomial \(P^{(\beta, \alpha)}_k(t)\).

The fast discrete Radon transform
[Proceedings] ICASSP-92: 1992 IEEE International Conference on Acoustics, Speech, and Signal Processing, 1992An explicit relationship between the continuous and discrete time Radon transforms is derived. A generalized least-squares solution to the inversion problem is proposed, and a new inverse counterpart to the fast Radon transform (FRT) algorithm (IFRT) is derived.

It was proved by J. Radon in 1917 that a differentiable function on R3 can be determined explicitly by means of its integrals over the planes in R3. Let J(ω, p) denote the integral of f over the hyperplane 〈x, ω〉 = p, ω denoting a unit vector and 〈,〉 the inner product.
