This document summarizes research on blood vessel segmentation in retinal images using MATLAB. It discusses using stationary wavelet transforms and neural networks to enhance vessels and classify pixels. The research aims to implement an effective algorithm using morphological processing and segmentation techniques to detect retinal vessels and exudates. It reviews related work applying techniques like fuzzy segmentation, matched filtering, and image mining. The document concludes that analyzing retinal vessels and exudates can help detect diseases early by comparing vessel states, and the presented algorithm effectively detects retinal blood vessels.
