REGULARIZATION PARAMETER SELECTION METHODS FOR ILL POSED POISSON IMAGING PROBLEMS
A common problem in imaging science is to estimate some underlying true image given noisy measurements of image intensity. When image intensity is measured by the counting of incident photons emitted by the object of interest, the data-noise is accurately modeled by a Poisson distribution, which …

View synthesis for kinetic depth X-ray imaging
… termed KDEX, previously undertaken by the Imaging Science Group at NTU. The ultimate aim of the research programme in collaboration with The UK Home Office and The US Dept. of Homeland Security is to enhance the detection and identification of threats in X-ray scans of luggage. A multi-view …

INVESTIGATION OF ADVANCED IMAGE RECONSTRUCTION ALGORITHMS FOR ELECTRON MICROSCOPY
… microscopy and introduces some basic concepts in imaging science. Chapter 2 takes a more in-depth discussion of elastic scattering in STEM and how beam propagation can be described analytically and computationally. The next two chapters focus on electron tomography, a technique that reconstructs …

Camera Spatial Frequency Response Derived from Pictorial Natural Scenes
… is a prominent part of many aspects of imaging science and computer vision. There are many aspects to camera performance that determines how accurately the image represents the scene, including measurements of colour accuracy, tone reproduction, geometric distortions, and image noise …

Small-volume monogenetic igneous landforms and edifices statistics (SMILES) of Earth and Mars: one morphometric framework to classify them all
… Terrian Models created from the High-Resolution Imaging Science Experiment and Context Camera imagery. The SMILES framework successfully classifies Martian scoria cones and spatter landforms from each other and non-volcanic features. The results demonstrate the utility of the SMILES framework for …

Investigations of the Martian Mid-Latitudes: Implications for Ground Ice
… exposed ice imaged by the High Resolution Imaging Science Experiment (HiRISE) camera. I discuss the theory of sublimation by free convection and describe a model that improves on the standard version used in the Mars literature. This model shows some differences from experimental data, but …
