Abstract (Summary)

In recent years, deep learning has seen a monumental growth in interest and research, and its applications have the potential to solve difficult analytical problems. This is particularly true for medical imaging, where analytical tasks can be time consuming, tedious, and require trained professionals, often incurring significant costs. One such task is that of segmenting vascular networks in retinal images. The state of retinal vascular networks plays an important role in ophthalmology where its analysis is the key in the early detection and diagnosis of various diseases. Segmentation is primarily challenging due to issues such as the low contrast of images, variety of vessels and potential pathologies.

To approach this task, experiments will integrate numerous techniques and designs from proven architectures into deep neural networks. Training and testing will be performed on two publicly available retinal datasets – DRIVE and STARE. When evaluated on each dataset, many of the networks achieve promising results, with one proposed variation of the U-Net architecture even surpassing the evaluated accuracy of its predecessors – benchmarking at 98.019% AUC ROC compared to the previous best of 97.9%.
