Background:

Retinal vessel detection is crucial for diagnosing ocular diseases.
Existing methods often fail to preserve vessel connectivity, impacting diagnostic accuracy.
Connectivity is vital for comprehensive retinal analysis.

Purpose of the Study:

To propose a novel method for accurate retinal vessel detection.
To address the issue of vessel discontinuity in current detection algorithms.
To enhance the diagnostic utility of retinal imaging through improved vessel segmentation.

Main Methods:

A dense dilated network with feature extraction blocks in an encoder-decoder structure was utilized for initial vessel detection.
A multi-scale Dice loss function was employed for network training.
A probability regularized walk algorithm was introduced to ensure vessel connectivity.

Main Results:

The proposed method demonstrated superior performance across three public datasets (DRIVE, STARE, CHASE_DB1).
Significant improvements were observed in accuracy, sensitivity, and specificity compared to state-of-the-art methods.
Enhanced vessel connectivity was achieved, addressing segmentation fractures.

Conclusions:

The novel method effectively detects retinal vessels with improved connectivity.
This approach offers a significant advancement for the diagnosis and treatment of ocular diseases.
The proposed technique provides more reliable and comprehensive retinal vessel segmentation.
