  • Employing anisotropic diffusion as a pre-processing step before ACO.
  • Applying the combined approach for optic disc detection in color fundus images.

    • Main Results:

    • The proposed method successfully detected the optic disc in a majority of the tested images.
    • The approach demonstrated good performance even with images exhibiting significant variability and pathologies.
    • This indicates a robust performance in challenging clinical scenarios.

    Conclusions:

    • The integration of anisotropic diffusion and Ant Colony Optimization offers a promising solution for automated optic disc detection.
    • This technique can enhance the efficiency and accuracy of diabetic retinopathy screening programs.
    • Further development could lead to more reliable automated diagnostic tools in ophthalmology.
