Segmentation of Blood Vessels in Fundus Color Images by Radon
In this paper we have presented an algorithm
for vessel detection in retinal color images which works based
on local Radon transform and morphological reconstruction.
In our previous work, the algorithm was applied to...
On the inverse of the directional derivative operator in RN
to straight line propagation of radiation emitted by the spatial source distribution ρ. In particular, we examine the special two-dimensional case to point out the connection with the classical Radon transform. We then show how the Radon transform inversion...
Robustness of Radon transform to white additive noise: general case study
The Radon transform inversion using moments
On the Generalized Quotient Integrals on Homogenous Spaces
A generalization of the quotient integral formula is presented and some of its
properties are investigated. Also the relations between two function spaces related to
the special homogeneous spaces are derived ...
The Radon transform on function spaces related to homogenous spaces
We are going to study some conditions on which the Radon transform
and its dual are invertible. Two function spaces are introduced that the Radon
transform on which is bijective linear operator. In this regards, a reconstruction...
Vessel Segmentation Based on Sobel Operator and Fuzzy Reasoning
and fuzzy inference. In the proposed method, the direction of linear structures are determined with Radon transform, then Sobel operator is used for extracting edges along with the predetermined direction. The combination of gradient information of vessel...

Vessel detection in retinal images using Radon transform and genetic algorithm
We propose a novel algorithm for vessel detection in
retinal images. The proposed algorithm incorporates Radon
Transform(RT) and Genetic Algorithm(GA) to detect vessels. We use
RT because vessels could ...
A Novel Algorithm for Linear Feature Detection in Images
We propose a novel algorithm for linear feature detection
in images. Our algorithm is an extension to Beamlet Transform(BT).
BT is a powerful transform for linear feature detection in images. It
is based on the famous Radon...
