Graph-enhanced deep learning for diabetic retinopathy diagnosis: A quality-aware and uncertainty-driven approach
Fig 5
Grad-CAM heatmaps were generated for retinal fundus images in the DR classification task.
Each row presents the original image, its corresponding Grad-CAM heatmap, and the model’s prediction. The red regions in the heatmaps indicate areas that strongly influence the classification. (a) represents our approach without any sophisticated preprocessing techniques, which performs significantly better than the other two: (b) with CLAHE preprocessing.
