Depth of field reduction for miniature-camera imaging
Cognard, Timothée E. (NUI Galway, 2020-08-25)This thesis investigates the reduction of depth-of- field for miniature camera systems, such as the ones embedded in smartphones. The work on digital shallow depth-of- field is already mature and implemented in most modern ... -
Detection of faint exoplanets in multispectral data
Hanley, Kenneth (NUI Galway, 2019-04-15)The detection of extrasolar planets is extremely difficult due to their extreme faintness and proximity to their parent stars. Direct, ground-based detection is particularly challenging and despite the incredible contrast ... -
Image super-resolution for consumer thermal cameras
Lynch, Colm (NUI Galway, 2019-01-21)This thesis attempts to solve a problem currently faced by consumer-grade thermal cameras. Consumers have grown accustomed to the high pixel counts and high resolution offered by the modern smartphone, while the performance ... -
Pre-processing, Registration and Quality Assessment of Adaptive Optics Assisted Retinal Images
Ramaswamy, Gomathy (2014-01-27)In recent decades, adaptive optics (AO) technology has been embedded into retinal imaging devices, producing a new generation of instrument, which can provide retinal images with cellular resolution. This new technological ... -
Processing of adaptive optics photoreceptor images and application to the study of healthy and diabetic retinas
Mariotti, Letizia (2017-11-17)The introduction of adaptive optics (AO) into vision science has made it possible for clinicians to study the human retina in vivo with high-resolution images. The study of AO images of the cone photoreceptor mosaic is ... -
Using spatial light modulators to investigate the limitations of adaptive optics performance for the European Extremely Large Telescope
Malone, Deborah Catherina (NUI Galway, 2024-02-02)The European Extremely Large Telescope (E-ELT) will be the world’s largest ground based optical / near-infrared telescope ever built. Its primary mirror, M1, will be 39 m in diameter and consist of 798 individual hexagonal ...
