- Abstract:
-
Segmentation of retinal blood vessels is an important step in the diagnosis of many early eye-related diseases. In this paper, the holistically-nested edge detection (HED) network is applied to retinal vascular image segmentation, and a series of improvements are made to the model: a new modified efficient channel attention (MECA) module is introduced to address the lack of ability of existing methods to identify edges and fine vessels, and a double residual structure is used to deepen the model structure to extract finer vascular structures. A structured DropBlock module is introduced to prevent overfitting problems from model deepening. In order to further improve sensitivity of the model, a short connection structure incorporating the MECA module is added in the feature fusion phase of the HED network. Experiments show that compared with the current state-of-the-art methods, the sensitivity of the proposed network is significantly improved, which indicates that the proposed method has the state-of-the-art ability to identify retinal vessels.
