Area of Science:

Ophthalmology
Medical Imaging
Computer Vision

Background:

Retinal vessel segmentation is crucial for diagnosing micro-vascular and ophthalmological diseases.
Challenges include variable vessel width and low contrast, hindering accurate segmentation.

Purpose of the Study:

To propose a novel multiscale feature interaction network (MFI-Net) for improved retinal vessel segmentation.
To enhance the network's ability to handle variations in vessel width and preserve fine details.

Main Methods:

Developed MFI-Net, a U-shaped convolutional neural network incorporating pyramid squeeze-and-excitation (PSE) and coarse-to-fine (C2F) modules.
The PSE module uses multiscale channel attention; the C2F module refines residual feature maps for detail preservation.

Main Results:

MFI-Net demonstrated superior segmentation performance and generalization ability across four public datasets (DRIVE, STARE, CHASE_DB1, HRF).
Both PSE and C2F modules were found to be effective in improving segmentation accuracy.

Conclusions:

MFI-Net offers a significant advancement in retinal vessel segmentation accuracy.
The proposed model shows strong potential for clinical applications in diagnosing eye conditions.
