Detection and Classification of Diabetic Retinopathy Pathologies in Fundus Images
… presented systems to detect pathology in retinal images. However, these approaches apply specialized algorithms to detect specific types of lesion in the retina. In order to detect multiple lesions, these systems generally implement multiple algorithms. Furthermore, some of these studies evaluate …

The manual analysis of human biometric identifiers in non-pathological retinal fundus images: An evaluation of presented methodologies and a survey of identifiers within open source databases
From the initial proposal of the use of retinal fundus images to enable human identification in 1935, identity biometrics based upon digital representations of the retinal fundus have been proposed as a highly effective modality applied for high level security applications. As complex internal …

Developing Interpretable Data Mining Frameworks for Addressing Biomedical Challenges in Genomics and Imaging
… latent and explicit information from retina fundus images to detect DR and identify DR stages. The methods discussed in this dissertation contribute to the research community by consolidating information and extracting hidden insights from publicly available data sources through interpretable …

Visual field and structural alterations in age-related macular degeneration
… the structure to function relationships between fundus images and the visual field were developed with computer programming and evaluated for repeatability. Drusen quantification of fundus photographs and retro-mode scanning laser ophthalmoscopic images was performed. Visual field progression was …

Building capacity for diabetic eye screening and management in low-middle income countries: a mixed-methods approach
… were more likely to systematically grader fundus images and use all available grading tools, such as the red-free filter to view more discrete signs of DR. Furthermore, high costs and distance to hospitals were two main barriers to DR screening and treatment uptake in Bangladesh and …

Applying Artificial Intelligence and Mobile Technologies to Enable Practical Screening for Diabetic Retinopathy
… to automatically predict DR using retina (fundus) images. However, the practical application of these algorithms is impeded by the different levels of DR severity, limited algorithm reproducibility, and a large variability in fundus imaging devices. To address these concerns, I present the …

Robust and Efficient AI-models for Medical Image Reconstruction, Segmentation, and Multimodal Knowledge Distillation
… accurate segmentation across multimodal medical images. To address the limitations of low-resolution imaging, particularly in resource-constrained environments such as spaceflight medicine, I introduce Swin-FSR, a Swin Transformer-based super-resolution model that reconstructs high-fidelity …

Retinal vessel segmentation using textons
Segmenting vessels from retinal images, like segmentation in many other medical image domains, is a challenging task, as there is no unified way that can be adopted to extract the vessels accurately. However, it is the most critical stage in automatic assessment of various forms of diseases (e.g. …

Metodo per la generazione del fondo retinico sintetico basato sull'estrazione delle caratteristiche
La distribuzione e l'analisi dei vasi sanguigni del bulbo oculare gioca un ruolo fondamentale nella diagnosi e nel trattamento di molte patologie come l'ipertensione e l'analisi del diabete. Pertanto, l'analisi delle immagini digitali vascolari retiniche ha un ruolo predominante nell'oftalmologia …
