3D-SkipDenseSeg

Skip-connected 3D DenseNet for volumetric infant brain MRI segmentation

By Toan Duc Bui, Jitae Shin, Taesup Moon

This is the implementation of our method in the MICCAI Grand Challenge on 6-month infant brain MRI segmentation-in conjunction with MICCAI 2017 in Pytorch.

Introduction

6-month infant brain MRI segmentation aims to segment the brain into: White matter, Gray matter, and Cerebrospinal fluid. It is a difficult task due to larger overlapping between tissues, low contrast intensity. We treat the problem by using very deep 3D convolution neural network. Our result achieved the top performance in 6 performance metrics.

Requirements:

• Pytorch >=0.4, python 3.0, Ubuntu 14.04
• TiTan X Pascal 12GB

Installation

• Step 1: Download the source code

https://github.com/tbuikr/3D-SkipDenseSeg.git
cd 3D-SkipDenseSeg

• Step 2: Download dataset at http://iseg2017.web.unc.edu/download/ and change the path of the dataset data_path and saved path target_path in file prepare_hdf5_cutedge.py

data_path = '/path/to/your/dataset/'
target_path = '/path/to/your/save/hdf5 folder/'

• Step 3: Generate hdf5 dataset

python prepare_hdf5_cutedge.py

• Step 4: Run training

python train_v2.py

Run evaluation result.

python val.py

We also provide pretrained model. Use the pretrained model, you should achieve the result as the table.
