Automatic segmentation of retinal vessels plays an important role in computer-aided diagnosis of ophthalmology and cardiovascular diseases. Attention mechanism can improve the efficiency and accuracy of image feature extraction in classical neural network models; so attention mechanism is widely used in retinal vessel segmentation models. This paper firstly reviews the commonly used datasets and evaluation metrics for retinal vessel segmentation; subsequently; attention mechanisms are categorized into two types: selective attention mechanisms and self-attention mechanisms; based on their working principles. Meanwhile; according to the data domain of computer vision tasks; attention methods are divided into three categories: channel attention; spatial attention; and mixed attention. Combined with the task of retinal vessel segmentation; the paper highlights the specific applications of representative attention models of these three types and conducts performance comparisons and evaluations of relevant models. Finally; the problems of attention mechanism and the development trend in the future are discussed. © 2024 Journal of Computer Engineering and Applications Beijing Co; Ltd; Science Press.
