초록

In this study, we propose a self-supervised learning framework for fundus image processing, utilizing both contrastive and generative learning techniques for pre-training. Our contrastive learning approach integrates both image and text modalities through cross-attention mechanisms, allowing the model to learn more informative and semantically rich representations. After pre-training, the model is fine-tuned for downstream tasks, including zero-shot, few-shot, and full fine-tuning. Experimental results show that our method significantly outperforms existing approaches, achieving 15% higher performance in zero-shot, 4.5% in few-shot, and 10.1% in fine-tuning scenarios. The proposed method demonstrates its potential in the medical imaging field, where access to large annotated datasets is often limited. By efficiently leveraging both image and textual information, our approach contributes to improving the accuracy and generalizability of models in fundus image analysis, highlighting its broader applicability in medical diagnostics and healthcare.
