    Area of Science:

    • Ophthalmology
    • Medical Imaging
    • Computer Vision

    Background:

    • Retinal fundus images are often uncalibrated in clinical settings.
    • Uncalibrated images present challenges in 3D reconstruction due to differences in radiometric properties and blur.
    • Accurate 3D structure recovery is crucial for diagnosing and monitoring retinal diseases.

    Purpose of the Study:

    • To develop a robust method for recovering the 3D structure of the optic disc from two uncalibrated retinal fundus images.
    • To address the challenges posed by uncalibrated stereo pairs in retinal imaging.
    • To improve the quality of fundus stereo reconstruction.

    Main Methods:

    • Modification of the Graph Cuts computational stereo method.
    • Exploitation of the retina's inherent structural characteristics.
    • Development of a high-quality algorithm for fundus stereo reconstruction.

    Main Results:

    • The proposed method achieves high-quality 3D reconstruction of the optic disc.
    • Experimental evaluations demonstrate superior performance compared to existing alternatives.
    • Validation using Optical Coherence Tomography (OCT) scans as 3D ground truth.

    Conclusions:

    • The novel Graph Cuts-based method effectively reconstructs 3D optic disc structure from uncalibrated fundus images.
    • This technique offers a significant advancement for 3D retinal analysis in clinical practice.
    • The method shows promise for improved diagnostic capabilities in ophthalmology.
