Addressing Occlusion in Panoptic Segmentation
… are still not completely robust to partial occlusion. In this work, we propose a novel object classification method based on compositional modeling and explore its effect in the context of the newly introduced panoptic segmentation task. The panoptic segmentation task combines both semantic …

Occlusion prediction for kiwifruit yield estimation
… suffered from sub-optimal performance due to occlusion of fruit. The work presented here introduces a system that has been developed with the aim of minimising occlusion where possible and employs an occlusion prediction model to account for remaining occlusion. The system utilises stereo …

Mathematical Models of Major Arterial Occlusion
The occlusion of a major artery constitutes a serious health concern as it can restrict blood flow and oxygen transport to dependent tissue regions. Fortunately, the vasculature surrounding the occlusion has mechanisms by which it can adapt to try to restore and maintain adequate perfusion to these …

Reasoning about objects under full occlusion
… estimation and object matching -- under full occlusion, and demonstrate superior performance over state-of-the-art methods. We also present a preliminary case study which demonstrates that our model is consistent with human behavior. Our work demonstrates a successful approach to a novel and …

Ambient occlusion and shadows for molecular graphics
… of advanced graphic effects such as ambient occlusion and shadows that greatly improve the comprehension of the 3D shapes of the molecules. This thesis focuses on finding improved solutions to the real time rendering of Molecular Graphics on modern day computers. The methods of calculating …

Microwave synthesis and occlusion reactions of zeolites
… of this thesis focuses on the ion exchange and occlusion reactions undergone by zeolites A (LTA), ZK-4 (LTA) and rho (RHO) in the presence of monovalent metal nitrates. In some cases non-framework peaks are seen in the powder X-ray diffraction patterns of occluded samples. These peaks are …

Occlusion of Dentin Tubules by Novel Prophylaxis Paste
Prophylaxis paste treatments are a standard part of biannual dental checkups. Prophylaxis pastes remove stains from teeth by polishing the surface of the enamel. Polishing essentially scratches the surface layer of enamel, thereby technically demineralizing teeth to achieve better aesthetics. The …

Effect of Occlusion, Directionality and Age on Horizontal Localization
… of hearing aid microphone technologies and occlusion separately and prior studies have not evaluated age as a factor in localization acuity. Open-fit hearing instruments provide new earmold technologies and varying microphone capabilities; however, these instruments have yet to be evaluated …

Anatomical and functional correlates in ischaemic retinal vein occlusion
Ischaemic retinal vein occlusion (RVO) is a potentially blinding condition that is not fully understood, and entails a higher risk of developing complications and poorer prognosis than non-ischaemic RVO. This PhD project was designed to improve the level of understanding on ischaemic RVO as well as …

Sex Differences in Collateral Remodeling Following Hindlimb Arterial Occlusion
… mechanisms is crucial. With arterial occlusions, necrosis and tissue injury can be naturally mitigated by the collateral circulation, improving patient prognosis. Previous sex-comparison studies describing differences in vascular remodeling are inconsistent. Therefore, the aim of this …

Face recognition under varying illumination, pose and contiguous occlusion
… variations in illumination, pose and contiguous occlusion, using only frontal training images. In particular, we are interested in simultaneously handling multiple modes of variability in automatic face recognition. We first propose a very simple algorithm, called Nearest-Subspace Patch Matching, …

Impacts of blood flow occlusion on the human neuromuscular system
Blood flow restricted or occlusion (BFO) exercise uses external pressure to impede blood flow, thus reducing the amount of oxygenated blood reaching the muscle, with greater pressure causing greater obstruction of blood flow. The result is enhanced muscle fatigability. The four studies in this …

Effects of Unilateral Extraction Treatment on Arch Symmetry and Occlusion
Occlusal asymmetries are common in orthodontic patients. A treatment option for correcting moderate asymmetries is asymmetric extractions. This study evaluated post-treatment dental arch symmetry in patients treated with unilateral premolar extractions. Post-treatment casts of 60 patients were …

Decreasing Occlusion and Increasing Explanation in Interactive Visual Knowledge Discovery
Lack of explanation and occlusion are the major problems for interactive visual knowledge discovery, machine learning and data mining in multidimensional data. This thesis proposes a hybrid method that combines visual and analytical means to deal with these problems. This method, denoted as FSP, …

Learning to handle occlusion for motion analysis and view synthesis
The ability to understand occlusion and disocclusion is critical in analyzing motion and forecasting changes. For example, when we see a car gradually blocks our view of a human figure, we know that either the car or the human is moving. We also know that the human behind the car will be visible …

Multi-Modal Ocular Recognition in presence of occlusion in Mobile Devices
… due to glasses reflection, shadow, and frame occlusion. In this regard, two operations (eyeglasses detection and eyeglasses segmentation) have been proposed to mitigate the effect of occlusion using eyeglasses. Eyeglasses detection is an important initial step towards eyeglass segmentation. …
