Project Caserel is an open-source software suite for computer-aided segmentation of retinal layers in optical coherence tomography 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). 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.
Above video illustrates the segmentation results by Caserel.
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 are not yet validated, 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.

Say it like casserole. The name is derived from "Computer-Aided SEgmentation of REtinal Layers in optical coherence tomography images".
