MedSeg: Medical Segmentation

Introduction

This repository contains code to train and evaluate 3D Convolutional Neural Networks for semantic segmentation on medical images. The architectures developed in this framework are a combination of auto-encoder UNet with shortcut connections as in ResNet, densely connections for deep supervision as in DensetNet and Merge-And-Run mapping for attention focusing as in MRGE.
