    Segmentation of Blood Vessels in Fundus Color Images by Radon 

    Type: Conference Paper
    Author : رضا پوررضاشهری; حمیدرضا پوررضا; touka Banaee; Reza Pourreza Shahri; Hamid Reza Pourreza
    Year: 2010
    Abstract:

    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 

    Type: Journal Paper
    Author : سید مجید صابری فتحی; T T Truong; Seyed Majid Saberi Fathi
    Year: 2009
    Abstract:

    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 

    Type: Journal Paper
    Author : Nacereddine, N.; Tabbone, Salvatore; Ziou, Djemel
    Publisher: IET
    Year: 2014

    The Radon transform inversion using moments 

    Type: Journal Paper
    Author : Mnatsakanov, Robert M. - Li, Shengqiao
    Publisher: Elsevier Science
    Year: 2013

    On the Generalized Quotient Integrals on Homogenous Spaces 

    Type: Journal Paper
    Author : تاج الدین دریکوند; رجبعلی کامیابی گل; محمد جانفدا; TAJEDIN DERIKVAND; Rajab Ali Kamyabi Gol; Mohammad Janfada
    Year: 2017
    Abstract:

    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 

    Type: Journal Paper
    Author : تاج الدین دریکوند; رجبعلی کامیابی گل; محمد جانفدا; TAJEDIN DERIKVAND; Rajab Ali Kamyabi Gol; Mohammad Janfada
    Year: 2018
    Abstract:

    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 

    Type: Conference Paper
    Author : فرنوش قدیری; محمدرضا اکبرزاده توتونچی; شهره حدادان; Farnoosh Ghadiri; Mohammad Reza Akbarzadeh Totonchi; Shohreh Haddadan
    Year: 2011
    Abstract:

    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...

    Offline Signature Verification Using Local Radon Transform and Support Vector Machines 

    Type: Journal Paper
    Author : وحید کیانی; رضا پوررضاشهری; حمیدرضا پوررضا; vahid kiani; Reza Pourreza Shahri; Hamid Reza Pourreza
    Year: 2009
    Abstract:

    Offline Signature Verification Using Local Radon Transform and Support Vector Machines...

    Vessel detection in retinal images using Radon transform and genetic algorithm 

    Type: Conference Paper
    Author : عادل قاضی خانی; حمیدرضا پوررضا; Adel Ghazikhani; Hamid Reza Pourreza
    Year: 2010
    Abstract:

    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 

    Type: Conference Paper
    Author : عادل قاضی خانی; حمیدرضا پوررضا; Adel Ghazikhani; Hamid Reza Pourreza
    Year: 2010
    Abstract:

    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...
