Extension Description

This extension is an open source tool to establish, optimize and visualize skeletal representation (abbreviated as s-rep) of 3D objects in biomedical images. The main features of this extension include:

• Establish an s-rep by mean curvature flow of an object boundary
  
• Refine an s-rep to fit an object boundary

•
