An algorithm for computing the discrete Radon transform with some applications
G.R. Ramesh, N. Srinivasa, Kasi Rajgopal · 2003
The enormous growth in the application areas of the Radon Transform and the fact that digital computations are of ten required, has led to the development of the Discrete Radon Transform ( DRT ). This paper proposes a method for computing the DRT by exploiting the converse of the Central Slice Theorem relating the Radon and Fourier Transforms, using the FFT algorithm. Simulation of the DRT algorithm is presented and some applications are discussed. The proposed algorithm can be extended for filtering in the Radon Space.
