 # segPLEX
-The algorithm is designed to be executed following the execution of 'convertPLEX' (https://github.com/cnzakimuena/convertPLEX).  Similarly as with 'convertPLEX', all previously processed folders containing all files (e.g. ‘SamplePatient_01’, ‘SamplePatient_02’, etc.) should be inserted into a 'processed' folder, which should be located inside the current directory.<br/>

 The segmentation of PLEX Elite 9000 retinal B-scan (size 3mm x 3mm) retinal-vitreous interface (RVI), top and bottom retinal pigment epithelium (RPE), and Bruch’s membrane (BM) is provided.  Two image segmentation algorithms are featured.  The first consists of a cross-sectional pre-segmentation using A-scan gradients and an implementation of Dijkstra's shortest path algorithm [1].  The second approach is a refinement of the pre-segmentation and involves a graph-cuts algorithm [2].  The segmentation algorithms were previously described and implemented on OCT images generated using a different device [3].<br/>
 An algorithm for structuring data into an Early Treatment Diabetic Retinopathy Study (ETDRS) grid [4] is also provided.<br/>
