Comparative analysis of existing glaucoma detection approaches
| Ref | Method / Model | Dataset | Key Contribution | Limitations |
|---|---|---|---|---|
| [16] | M-LAP Model | Fundus Images | Multi-scale feature extraction for glaucoma detection | Difficulty in accurate optic cup segmentation |
| [19] | SVM-based Classification | Retinal fundus images | Uses retinal blood flow features for glaucoma classification | Requires large datasets for effective training |
| [20] | GSO Algorithm | Fundus Images | Automatic optic cup detection using intensity gradients | Performance affected by low-resolution images |
| [21] | Geometric Feature Model | Digital fundus images | Optic disc segmentation using computer vision methods | Sensitive to illumination and intensity variations |
| [23] | CNN-based CAD Model | Fundus Images | Automated glaucoma detection using deep learning | Limited training samples and incomplete attention mapping |
| [25] | AG-CNN | LAG Dataset | Attention-based CNN improves convergence and robustness | Reduced AUC and incomplete attention coverage |
