This extension is for segmentin lung tissue CT according to intensity.

Module Description

This module, given a chest CT, segment lung tissue by fitting the intensities with a Gaussian Mixture Model already created. It can be used for pneumonia (COVID-19 too).

Use Cases

• Lung CT GMM Segmentation

User wants to segment lung tissue according to intensity (healthy, ground-glass opacities, and consolidation).
