This study introduces a novel multi-scale method for automated retinal vessel segmentation in fundus images. The technique accurately identifies vessel centerlines and radii, improving diagnostic capabilities.

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Computer Vision

Background:

  • Automated segmentation of retinal vessels is crucial for diagnosing various eye conditions.
  • Existing methods face challenges with noise and vessel connectivity in optic fundus images.

Purpose of the Study:

  • To propose a novel multi-scale method for accurate retinal vessel segmentation.
  • To enhance the extraction of vessel centerlines and radii from optic fundus images.

Main Methods:

  • A weighted two-dimensional (2D) medialness function is utilized.
  • Multiplication with Hessian matrix eigenvalues and noise reduction are applied.
  • Centerline extraction, vessel radius estimation, and segmentation are performed.

Main Results:
