Retinal Blood Vessel Segmentation with Attentive Feature Fusion

This study investigates the utilization of sophisticated deep learning techniques, specifically, the integration of UNet and ResNet models with attention processes, to improve the accuracy of retinal blood vessel segmentation in fundus images. It focuses on the urgent requirement for accurate and effective segmentation methods in the diagnosis and monitoring of disorders connected to eyesight. The work introduces a new method that combines UNet's semantic segmentation capabilities with ResNet's gradient problem avoidance to overcome the constraints of previous segmentation approaches. Incorporating attentive feature fusion and a transformer bridge enhances the model's capacity to concentrate on pertinent image characteristics and gather broader contextual information that is essential for precise vessel segmentation. The study encompasses a thorough approach that encompasses data collection, model structure construction, training techniques, and performance assessment criteria. The results indicate that the model outperforms existing techniques in terms of accuracy, sensitivity, specificity, and F1 score. This has significant implications for clinical applications in ophthalmology. It highlights the significance of employing advanced methodologies in the interpretation of medical images and delineates potential areas for additional enhancement and wider implementation. In summary, the study introduces a very efficient and encouraging method for dividing retinal blood vessels, which has the potential to improve the accuracy of diagnoses and the quality of care for patients in the field of ophthalmology.
