Bayesian Methods for Gas-Phase Tomography
(University of Waterloo, 2018-09-10)Gas-phase tomography refers to a set of techniques that determine the 2D or 3D distribution of a target species in a jet, plume, or flame using measurements of light, made around the boundary of a flow area. Reconstructed ... -
Comparison of super-resolution algorithms applied to retinal images
(Society of Photo Optical Instrumentation Engineers, 2014-05-01)A critical challenge in biomedical imaging is to optimally balance the trade-off among image resolution, signal-to-noise ratio, and acquisition time. Acquiring a high-resolution image is possible; however, it is either ... -
Compressed Sensing in the Presence of Side Information
(University of Waterloo, 2012-08-01)Reconstruction of continuous signals from a number of their discrete samples is central to digital signal processing. Digital devices can only process discrete data and thus processing the continuous signals requires ... -
Determining relaxation times for porous media: Theory, measurement, and the inverse problem
(University of Waterloo, 2007-08-03)This thesis provides an introduction to and analysis of the problem of determining nuclear magnetic resonance (NMR) relaxation times of porous media by using the so-called Carr-Purcell-Meiboom-Gill (CPMG) technique. We ... -
Developments Towards Chromophore-Selectivity in Photoacoustic Remote Sensing Microscopy
(University of Waterloo, 2022-04-28)Medical imaging serves to diagnose and monitor illnesses in clinical settings. Several modalities such as X-Ray and Ultrasound have become ubiquitous due to their high utility. Photoacoustic microscopy, based on the ... -
Monitoring Oil Reservoir Deformations by Measuring Ground Surface Movements
(University of Waterloo, 2010-01-21)It has long been known that any activity that results in changes in subsurface pressure, such as hydrocarbon production or waste or water reinjection, also causes underground deformations and movement, which can be described ... -
Numerical Demultiplexing of Color Image Sensor Measurements via Non-linear Random Forest Modeling
(University of Waterloo, 2016-06-20)Due to recent advancements in technology, consumer digital cameras are becoming cheaper and easier to use. These consumer digital cameras, with Bayer color filter arrays (CFAs), allow for simultaneous capture of the red, ...
