The code provides image reading from raw Spectralis(.vol) and Cirrus(.img) and Matlab files (.mat). It supports retina flatten, cropping, reconstruction and visualization e.t.c
We provide Matlab preprocessing steps and results in the papers:
Fully Convolutional Boundary Regression for Retina OCT Segmentation (MICCAI2019)
Deep learning based topology guaranteed surface and MME segmentation of multiple sclerosis subjects from retinal OCT (BOE2019)

Healthy and MS evaluation: Run
hc_eval.mTraining: hc09-hc14 and ms13-ms21 (6 healthy and 9 MS, hc09, ms13, ms14 can be used for validation) Testing: hc01-hc08 and ms01-ms12 (8 healthy and 12 MS)
-
DME evaluation: Run
dme_eval.mStandard 50%-50% split are used as in the literature with a fixed training epoch.
