Abstract

Glaucoma represents a significant global contributor to blindness. Accurately segmenting the optic disc (OD) and optic cup (OC) to obtain precise CDR is essential for effective screening. However, existing convolutional neural network (CNN)-based segmentation techniques are often limited by high computational demands and long inference times. This paper proposes an efficient end-to-end method for OD and OC segmentation, utilizing the lightweight MobileNetv3 network as the core feature-extraction module. Our approach combines boundary branches with adversarial learning, to achieve multi-label segmentation of the OD and OC. We validated our proposed approach across three public available datasets: Drishti-GS, RIM-ONE-r3, and REFUGE. The outcomes reveal that the Dice coefficients for the segmentation of OD and OC within these datasets are 0.974/0.900, 0.966/0.875, and 0.962/0.880, respectively. Additionally, our method substantially lowers computational complexity and inference time, thereby enabling efficient and precise segmentation of the optic disc and optic cup.

基于 MobileNetv3 卷积神经网络的轻量级视盘和视杯分割。
青光眼是导致全球失明的重要原因。准确分割视盘(OD)和视杯(OC)以获得精确的 CDR 对有效筛查至关重要。然而,现有的基于卷积神经网络(CNN)的分割技术往往受到计算要求高和推理时间长的限制。本文利用轻量级 MobileNetv3 网络作为核心特征提取模块,提出了一种高效的端到端 OD 和 OC 分割方法。我们的方法将边界分支与对抗学习相结合,实现了 OD 和 OC 的多标签分割。我们在三个公开数据集上验证了我们提出的方法:Drishti-GS、RIM-ONE-r3 和 REFUGE。结果显示,在这些数据集中,OD 和 OC 分割的 Dice 系数分别为 0.974/0.900、0.966/0.875 和 0.962/0.880。此外,我们的方法大大降低了计算复杂度和推理时间,从而实现了对视盘和视杯的高效、精确分割。
