Image processing

The School of Physics has research interests in methods to process images associated with the collection, analysis and display of scientific data. This interest arose historically from experimental work on two-dimensional scattering data in nuclear physics, which has since become centered on x-ray or medical imaging. Of particular interest are algorithms for discrete image processing and how these apply to discrete geometry. This includes the limitations on traditional computed-tomography (CT) image precision, three-dimensional x-ray tomography, sparse-data reconstructions and use of the Discrete Radon Transform (DRT) as a tool for image reconstruction and analysis. Algorithms have also been developed to process multi-spectral data, using a novel combination of linear and morphological rank-order statistics. The latter ideas have been applied to quantify the effects of algorithms for the high fidelity display of digital images that are captured with a very high dynamic range, and to examine changes in cell morphology arising from micro-beam radiation therapy.
