Multiple Surface Segmentation of the Retinal Layer in OCT Images

Data

Preprocessed data for this experiment were provided by Charit´e University Hospital Berlin.
Data consist of the images of 53 healthy eyes. Each eye contains 47-49 scans (images) which makes 2597 images in total.
We are not allowed to upload data and use outside of the class.

Methods

We have compared 2 methods, which were proposed for medical image segmentation, namely UNet and CNN-S.
UNet code was forked from https://github.com/milesial/Pytorch-UNet

Results:
