Area of Science:

Medical Imaging
Artificial Intelligence
Ophthalmology

Background:

Retinal blood vessel segmentation is crucial for diagnosing eye conditions like glaucoma and macular degeneration.
Existing methods face challenges with image noise and data limitations.

Purpose of the Study:

To develop and evaluate a robust framework for accurate retinal blood vessel segmentation.
To improve diagnostic support for various ocular diseases through enhanced image analysis.

Main Methods:

A two-stage framework involving multi-layer preprocessing and U-Net segmentation with attention.
Preprocessing includes noise reduction (CNN with MF, D_U-Net), data imputation, and data augmentation (LDM).
Segmentation utilizes a U-Net with a multi-residual attention block for precise vessel identification.

Main Results:

The framework achieved high performance metrics: Dice score (95.32%), accuracy (93.56%), precision (95.68%), and recall (95.45%).
Effective noise reduction was demonstrated via PSNR and SSIM values across various noise levels.
Latent Diffusion Model (LDM) showed strong performance in data augmentation with an inception score of 13.6 and FID of 46.2.

Conclusions:

The proposed framework significantly enhances retinal blood vessel segmentation accuracy.
The multi-stage approach effectively addresses preprocessing challenges, leading to reliable diagnostic information.
This method offers a promising tool for clinical ophthalmology and research.
