Multi-task-deep-network

Multi-task deep learning based approaches for semantic segmentation in medical images

Psi-Net: Shape and boundary aware joint multi-task deep network for medical image segmentation (EMBC 2019) Conv-MCD: A Plug-and-Play Multi-task Module for Medical Image Segmentation (MICCAIW - MLMI 2019)

Dependencies

Packages

PyTorch
TensorboardX
OpenCV
numpy
tqdm

An exhaustive list of packages used could be found in the requirements.txt file. Install the same using the following command:

 conda create --name <env> --file requirements.txt

Preprocessing

Contour and Distance Maps are pre-computed and can be obtained from binary mask. Sample matlab codes can be found here:

Contour: https://in.mathworks.com/help/images/ref/bwperim.html
Distance: https://in.mathworks.com/help/images/ref/bwdist.html
