This is the main page of project Caserel, an open-source software suite for computer-aided segmentation of retinal layers in optical coherence tomography (OCT) images written in Matlab.
Currently, the software supports segmentation of 6 retinal layers by automatically delineating 7 boundaries (ILM, NFL/GCL, IPL/INL, INL/OPL, OPL/ONL, IS/OS,RPE) from OCT images. An image browser/editor is provided for manual and semi-automated correction of the segmented retinal boundaries. For a quick demonstration, please run script 'getRetinalLayersExample.m'.
Please note that this project is "work-in-progress", meaning many features still needs to be implemented, e.g. detection of macula and vessels . In addition, the accuracy of the automated segmentation is not completely evaluated, so if you are to use the resulting segmentation for quantification of retinal layer thickness, I recommend carefully reviewing the segmentation results using either the provided GUI or other image segmentation tools.
