| dc.description.abstractEn | Purpose : Retinal vessels analysis is crucial for early identification, diagnosis, and continuous monitoring of eye diseases. The extraction of quantitative metrics, such as width and tortuosity provides insights into a patient's overall health. The process of measuring vessels involves at first a necessary image processing step known as segmentation. The objective is to address limitations in current retinal vessels segmentation methods, particularly in the context of a scarcity of labeled images for training efficient Deep Learning algorithms. Methods : The proposed approach introduces four innovative methods specifically designed for arteries, veins, optic disk, and vessels as a whole. The segmentation process is streamlined, demanding only ten images of a specific dataset as input. This method aims to overcome the challenges posed by manual labeling's time-consuming nature and the inefficiency of current algorithms in scenarios with limited labeled images. Such scenarios are named Few-Shot learning and the Deep Learning algorithms we designed are dedicated to this purpose. The architecture of our four algorithms are derived from the well-known encoder-decoder U-Net, which cannot detect a single vessel in Few-Shot scenarios. We incorporate batch normalization to this architecture to solve two issues. First stabilizing the training with normalized data to avoid divergence of the learning process due to a lack of similarity between the data, which is a problem faced with few images. Then enhancing the prediction in real-world scenarios by avoiding using the learned normalization statistics. We made modifications to the depth of the architecture and the feature map space to further enhance details-gathering. Results : The method's efficacy is demonstrated with high superposition correspondence to manually labeled images: 69% for arteries, 73% for veins, 81% for vessels, and an outstanding 86% for the optic disk. These results showcase the breakthrough in addressing the limitations of existing techniques, especially in real-world conditions with a dearth of labeled images. Conclusions : In conclusion, the proposed method offers a significant advancement in retinal vessels segmentation. By reducing the dependency on a large number of manually labeled images and achieving remarkable superposition, this approach opens new possibilities for efficient and trustful retinal vessels analysis in diverse clinical scenarios.
