[NOTE] Since this project has upgraded to Tensorflow 2.3 on 18th March 2021, you can find old branches which have stopped maintenance from:

• [2019-6-9] keras-tensorflow branch: https://github.com/DeepTrial/Retina-VesselNet/tree/keras-tensorflow-1.X
• [2018-5-2] keras-theano branch: https://github.com/DeepTrial/Retina-VesselNet/tree/keras-theano

A Simple U-net model for Retinal Blood Vessel Segmentation with DRIVE dataset

We provide 2 version of projects: jupyter notebook and .py file. The implementation of these two versions is completely consistent. Choose one version and enjoy it!

For the first time, I recommand to use the version of jupyter notebook, it will give you an intuitive presentation. Different notebooks are made for different purpose:

• EntireBookForColab.ipynb contains complete part of projects such as process, train, test. Furthermore, it can be run on Google Colab
• PreprocessIllustartion.ipynb shows some preprocess methods for retinal images.
• TestAndEvaluation.ipynb is the part for evaluating and testing the model.
• Training.ipynb is the part for defining and training the model.

Remenber to modify the dataset path according to your setting.

• Dataset can be found here. For Chinese, you can download here.
• Pretrained model is coming soon...

If you want to test your own image, put your image to the the relevant dir and adjust the patch_size,stride according to your image size.
