Abstract
Provided are a method and system for identifying and classifying the owner, age and health of an optic nerve head and its vasculature based on analysis of vector relationships of blood vessels and the neuroretinal rim within an image of the optic nerve head to each other.
Claims15
A computer-implemented method of classifying the optic nerve head, the method comprising operating one or more processors to:
- segment an image of an optic nerve head from a photographic image of an eye;
- segment the image of the optic nerve head into multiple segments each containing blood vessels and neuroretinal rim fibres;
- extract features from the segmented images, the features describing relationships between the blood vessels themselves and between the blood vessels and the neuroretinal rim fibres in each of the segmented images, wherein the relationships between the vessels themselves and between the blood vessels and the neuroretinal rim comprise vectors mapped between points on the blood vessels and the neuroretinal rim in each of the segmented images;
- identify characteristics of the optic nerve head based on the extracted features;
- and
- classify the image of the optic nerve head based on the identified characteristics.
