UNet-Zoo

A collection of UNet and hybrid architectures for 2D and 3D Biomedical Image segmentation, implemented in PyTorch.

This repository contains a collection of architectures used for Biomedical Image Segmentation, implemented on the BraTS Brain Tumor Segmentation Challenge Dataset. The following architectures are implemented

1. UNet - Standard UNet architecture as described in the Ronneberger et al 2015 paper [reference]

1. Small UNet - 40x smaller version of UNet that achieves similar performance [Theano Implementation]

1. UNet with BDCLSTM - Combining a BDC-LSTM network with UNet to encode spatial correlation for 3D segmentation [reference]

1. kUNet - Combining multiple UNets for increasing heirarchial preservation of information (coming soon) [reference]
2. R-UNet - UNet with recurrent connections for another way to encode $z$-context (coming soon)

To Run

First, apply for access the BraTS Tumor dataset, and place the scans in a Data/ folder, divided into Train and Test. Feel free to modify the BraTS PyTorch dataloaders in data.py for your use.

1. UNet - run main.py, type --help for information on arguments. Example: python main.py --train --cuda --data-folder "./Data/"
2. Small UNet - run main_small.py, and use --help
3. BDC-LSTM - run main_bdclstm.py and use the weights for either your trained UNet or Small-UNet models (--help is your savior).
