Demonstration of graph-based segmentation of retinal layers in an optical coherence tomography image



View License

This script demonstrates how graph theory can be used to segment retinal layers in optical coherence tomography images.
run the script by pressing F5.
I am working on a more comprehensive open source software package for computer-aided segmentation of retinal layers in optical coherence tomography images, which currently includes 1. automated segmentation of 6 reitnal layers and 2. GUI for examination and manual correction of the automated segmentation. It can be downloaded at my github page.

@Bashir Isa Dodo, this code does not support opening of zip files, try unzipping the zip file and using the files within the zip file.

Hello, I tried running the code, by entering the folder path of the images, but I always get this error
>> updatedGTherorySimplified
Error using load
Unable to read file 'D:\Matlab'. No such file or directory.

Error in updatedGTherorySimplified (line 35)
load([folderPath imageDir(1).name]);
and I am sure the images are in the directory, I tried copying the images to separate directory, and still no change
Hope to get a feedback thanks
