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
