Project Description

Objective

• Generate effective visualizations for 3D SIFT feature sets in Slicer.

Approach, Plan

• Investigate methods for visualizing 3D feature location, scale, orientation and group label (e.g. diseased, healthy)
• Location, scale: spheres (markups), group labels: color/transparency
• Visualization: Slicer Python module based on Slicer Markups
• Data preparation: c++

Progress

• Evaluated Slicer fiducials and VTK glyph models for feature display
• Developed a python script to convert a 3D SIFT feature file into a VTK model (thanks Lauren, Nicole)
• ToDo:
  • display feature orientation (possibly as another glyph)
  • display varying feature opacity
