This repository includes diverse algorithmic method of model-based medical image segmentation.
The terminology of model-based means one which is hypothesized and parameterized model,
so it is a bit free from the requirement of plenty of labeling data (the counter example is usually called data-driven method).

The below list describes the classification of model-based method and the representative models belonging to it.

• Region-Based
  • Region Growing
  • Grow-Cut
• Active Contour
  • Snake Model
  • Gradient Vector Flow
• Level-Set
  • Level-set Method
  • Chan-Vese Model
  • Morphological Chan-Vese Model
  • Region Scalable Fitting Method (RSF)
  • Distance Regularized Level Set Evolution (DRLSE)
  • Kullback-Leibler-Based Level-set Method (to be updated)
• Graph-Based
  • Graph-Cut
  • Simulated Annealing Method
  • Random Walker with Prior Model
  • Power Watershed Random Field (to be updated)
• Clustering
  • Gaussian Mixture Model
  • Taboggan/Superpixel Clustering

You can simply use functions in this repository by cloning repository,

{user}@{work-node}: {workplace}$ git clone https://github.com/swyang50066/segmentation.git

or using below command.

{user}@{work-node}: {workplace}$ sudo pip install git+https://github.com/swyang50066/segmentation.git 

Usage of segmentation models is guided in './examples/xxxx.ipynb' with example runs, so please refer to the scripts to figure out how the models work!

All codes have developed in python and tested with python>=3.6.0 environment (but, it stably supports functions with python==3.8.0). Numerical schemes (e.g., matrix operation, linear algebra, graph algorithm, ... etc.) used in the models is designed with numpy and scipy modules for efficient computing.

 requirements={
 	"python>=3.6.0",
 	"opencv-python>3.4.0",
 	"numpy>=1.18.0",
 	"scipy>=1.1.0",
 	"scikit-learn>=0.20.0",
 	"scikit-build>=0.12.0",
 	"opencv-python>3.4.0",
 	"PyMaxFlow>=1.2.0",
 }

1. Build a GUI application for user-interactive medical image segmentation
2. Upload Power Watershed Random Field model

Updates are being delayed due to busy life.
