Design and development of a 3D X-ray microscope
… on the inverse Radon transformation and the Fourier slice theorem were used to regenerate conventional CT images as well as contrast volumetric 3D images of the internal structures of opaque objects. This paper presents the design and development of the 3D x-ray microscope together with …

Digital image processing of orbital synthetic aperture radar
… frequency domain, uses a technique based on the Fourier slice theorem, and in this thesis a previously reported ambiguity is confirmed and analysed. The development of a new Radon transform is described, which enables transformation into Radon space (for contrast enhancement), and back into image …

Fast and Scalable Architectures and Algorithms for the Computation of the Forward and Inverse Discrete Periodic Radon Transform with Applications to 2D Convolutions and Cross-Correlations
… or its inverse, involves the use of the Fast Fourier Transform, with the inherent approximation/rounding errors and increased hardware complexity due the need for floating point arithmetic implementations. An alternative implementation of the DRT is through the use of the Discrete Periodic …

Detection and Localization of Linear Features Based on Image Processing Methods
<p>In this work, the general problem of the detection of features in images is considered. One of the methods, the orientation detection of lines, utilized the Radon transform (sinogram) of an image to detect lines at different angles in an image. The line thickness algorithm was generated by …
