Radon transform inversion via Wiener filtering over the Euclidean motion group
In this paper we formulate the Radon transform as a wnvolution integral over the Euclidean motion group (SE(2)) and provideaminimummean square error(MMSE) stochastic deconvolution method for the Radon transform inversion. Proposed approach provides a fundamentally new formulation that can model nonstationary signal and noise fields. Key components of our development are the Fourier transform ov...
متن کاملInverse Problems in Imaging Systems and the General Bayesian Inversion Frawework
In this paper, first a great number of inverse problems which arise in instrumentation, in computer imaging systems and in computer vision are presented. Then a common general forward modeling for them is given and the corresponding inversion problem is presented. Then, after showing the inadequacy of the classical analytical and least square methods for these ill posed inverse problems, a Baye...

Plenoptic imaging systems with a microlens array imaging the pupil at the sensor typically produce low resolution images. We introduce an inverse problem solver using the system response to obtain high resolution image reconstructions.

متن کاملA Wiener Filtering Approach over the Euclidean Motion Group for Radon Transform Inversion
The problem of Radon transform inversion arises in fields as diverse as medical imaging, synthetic aperture radar, and radio astronomy. In this paper, we model the Radon transform as a convolution integral over the Euclidean motion group and provide a novel deconvolution method for its inversion. The deconvolution method presented here is a special case of the Wiener filtering framework in abst...
متن کاملDetermination of Fiber Direction in High Angular Resolution Diffusion Images using Spherical Harmonics Functions and Wiener Filter
Diffusion tensor imaging (DTI) MRI is a noninvasive imaging method of the cerebral tissues whose fibers directions are not evaluated correctly in the regions of the crossing fibers. For the same reason the high angular resolution diffusion images (HARDI) are used for estimation of the fiber direction in each voxel. One of the main methods to specify the direction of fibers is usage of the spher...
