Retina Vessel Segmentation based on Frangi vesselness filter and UNet architecture.

I propose the following pipeline in order to perform vessel segmentation :

A preprocessing step which consists to enhance vessels structures with a Frangi filter.
A UNet architecture to learn a segmentation model.

This repo contains :

A notebook about retina vessel enhancement with Frangi vesselness filter.
Python files to train a UNet network for performing segmentation.
