    This study introduces a novel Rider-based Gaussian approach for precise retinal blood vessel tracking and diameter estimation. The method significantly improves accuracy in analyzing retinal structures for early disease detection.

    Area of Science:

    • Ophthalmology
    • Medical Imaging
    • Computational Biology

    Background:

    • Retinal blood vessel analysis is crucial for diagnosing ocular diseases like diabetic retinopathy.
    • Accurate tracking and diameter estimation of these vessels remain a significant challenge in retinal structure analysis.

    Purpose of the Study:

    • To develop an accurate method for tracking retinal blood vessels and estimating their diameter.
    • To improve the detection of ocular diseases through enhanced retinal structure analysis.

    Main Methods:

    • A Rider-based Gaussian approach was developed, modeling vessel diameter and curvature as Gaussian processes.
    • Features for Gaussian process training were determined using Radon transform.
    • The Rider Optimization Algorithm optimized Gaussian process hyperparameters for vessel direction evaluation and bifurcation detection.

    Main Results:

    • The proposed method achieved high performance with a standard deviation of 0.2499 and a mean average of 0.0147.
    • It outperformed the state-of-the-art method by 6.32% in analyzing normal blood vessels.
    • Performance was validated on the Structured Analysis of the Retina (STARE) Database.

    Conclusions:

    • The Rider-based Gaussian process offers a promising advancement for accurate retinal blood vessel analysis.
    • Future research should focus on extending the method to include tortuous vessels found in various retinopathy patients.
