摘要:

青光眼是一种常见的眼科疾病,若不及早发现将导致不可逆的失明。因此,早期检测青光眼对于制定更好的治疗方案和最终挽救视力至关重要。最近的文献表明,基于CNN的方法在从视网膜眼底图像中检测青光眼方面具有显著优势。然而,这些方法主要集中于解决二分类任务,尚未充分探索不同青光眼阶段的检测,由于微小的病变大小变化和高类间相似性,这相对具有挑战性。本文提出了一种基于全局自注意力的网络,称为GS-Net,用于高效的多阶段青光眼分类。我们引入了一个全局自注意力模块(GSAM),包含两个并行注意力模块:通道注意力模块(CAM)和空间注意力模块(SAM),以学习跨通道和空间维度的全局特征依赖关系。GSAM有助于从眼底图像中提取更具判别性和类别特异性的特征。在公开数据集上的实验结果表明,我们的GS-Net优于现有最先进的方法。此外,GSAM在与流行的注意力模块对比中也取得了有竞争力的性能。

英文摘要:

Glaucoma is a common eye disease that leads to irreversible blindness unless timely detected. Hence, glaucoma detection at an early stage is of utmost importance for a better treatment plan and ultimately saving the vision. The recent literature has shown the prominence of CNN-based methods to detect glaucoma from retinal fundus images. However, such methods mainly focus on solving binary classification tasks and have not been thoroughly explored for the detection of different glaucoma stages, which is relatively challenging due to minute lesion size variations and high inter-class similarities. This paper proposes a global self-attention based network called GS-Net for efficient multi-stage glaucoma classification. We introduce a global self-attention module (GSAM) consisting of two parallel attention modules, a channel attention module (CAM) and a spatial attention module (SAM), to learn global feature dependencies across channel and spatial dimensions. The GSAM encourages extracting more discriminative and class-specific features from the fundus images. The experimental results on a publicly available dataset demonstrate that our GS-Net outperforms state-of-the-art methods. Also, the GSAM achieves competitive performance against popular attention modules.
