Retinal Vessel Image Segmentation and Three-dimensional Reconstruction of Retinal Vessel

Abstract

Retinal vessel appearance is an important indicator for many early diagnoses,including diabetes,hypertension, and arteriosclerosis.Computer processing can help doctors' work and a retinal vessel image segmentation algorithm was proposed.A local normalization algorithm was used to eliminate background differences.Expectation-maximization algorithm was used to classify the pixels into several classes to obtain segmentation results.At last,based on the anatomical and physiological characteristics of the eye,a reconstruction method to reconstruct three-dimensional retinal vessel was realized by inverse projection theory.The model can be viewed from different directions.
