Graph-based segmentation of retinal layers in oct images
This script demonstrates how graph theory can be used to segment retinal layers in optical coherence tomography images.
USAGE:
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. http://pangyuteng.github.io/caserel

How can we segment the rest of the layers?Like choroid, it's five layer, retina, it's 10 layers and Chorioscleral interface the CSI.
I am applying the code given at http://pangyuteng.github.io/caserel for my own image but finding this error. kindly tell me why.
**Attempt to reference field of non-structure array.
Error in getRetinalLayersCore (line 114)
indPathX = find(rPaths(strcmp('ilm',{rPaths.name})).pathY==k);
Error in getRetinalLayers (line 129)
[retinalLayers, ~] = getRetinalLayersCore(retinalLayerSegmentationOrder{layerInd},imgNew,params,retinalLayers);
Error in getRetinalLayersExample (line 107)
[retinalLayers, params] = getRetinalLayers(img);**
@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 TrialsCMF_v1.0.zip'. 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
