Abstract
Optical coherence tomography angiography (OCTA) is a non-invasive imaging technique, and automatic segmentation of retinal vessels is crucial for understanding ocular diseases and making informed clinical decisions. However, the automatic segmentation of retinal vessels in OCTA images is particularly challenging due to several inherent issues. Retinal vessels often exhibit low contrast against the surrounding tissue, making it difficult to distinguish them clearly. Additionally, the complex and irregular branching structures of retinal vessels, along with the presence of noise and artefacts in OCTA images, further complicate the segmentation task. To address these challenges, we propose a novel method, the spatial and multi-frequency domain-based segmentation network (SMFDNet), specifically designed for vessel segmentation in OCTA fundus images. This network effectively combines spatial and multi-frequency domain features to enhance the segmentation accuracy of retinal vessels. To demonstrate the superiority of our proposed network, we conduct experiments on the Retinal Vessels Images in OCTA (REVIO), Retinal OCT-Angiography Vessel Segmentation (ROSE) and Optical Coherence Tomography Angiography-500 (OCTA-500) datasets. The extensive experimental results show that our approach consistently outperforms state-of-the-art methods, particularly in handling low contrast and complex vessel structures. The codes are available at https://kyanbis.github.io/SMFDNet/.
