Slicer:Developer Meetings:20050301

Slicer Developers Meeting

March 1, 2005, 2-3pm, at 1249 Boylston St., second floor demo room.

Topic: Recap of the NA-MIC meeting

Present: Steve Pieper, Nicole Aucoin, Haiying Liu, Sonja Pujol, Katie Hayes, Mike Halle.

• the remodel of the 1249 Boylston office space is going to go ahead
• Andy Cedilnik should be here on Monday to work on redoing Slicer's build process, Steve will confirm
• Level sets for segmentation?
  • Karl did VTK level sets
  • Karl and Raul did itk, it's going into ITK
  • fast marching by Eric Pichon, moving inot ITK as well
  • seed based (with fiducials) segmentation with underlying ITK
  • preview window for filters?
    • use subvolume module?
    • framework for itk filters is needed
• NA-MIC: set up dti, then frmi in ITK
• DTI class done by Jessica Turner at UCI, Michelle Perry at UCSD
• Qball in Slicer now for ODF visualisation
• spatial objects
• Matlab integration issues
  • Core 1 and 3 of NA-MIC use it, 2 doesn't use it
  • conversion path?
  • conventions
  • Octave? not as much support
  • what do they use it for most?
  • MEX to get C code for distributable Matlab binaries, need Matlab install of the demo version in order to run your binary
  • can ship ITK images/code to Matlab
• vnl in slicer via ITK (templated), Raul's module for tensor reconstruction (Lauren doing clustering, direct)
• things the NA-MIC toolkit can offer:
  • inherently parallel
  • works for large memory requirement problems
  • database access

Future Slicer Projects

• Mike: Michelle Porkin from Harvard/Smithsonian Astrophysics Observatory
  • wants an astrophysics data reader for itk
  • then put astro data in slicer for visualisation
  • namic project
  • support multichannel (multi wavelength) data
  • from Chandra X-ray Observatory, pipeline to transfer coordinate systems
• Katie: Jeremy interested in using for visualising sonar data
  • use itk
  • proprocess from polar coordiantes for autonomous submarine surveys
• NA-MIC driving applications now rather than core
  • stereo matching could go in
  • star matching
• Sylvain put his uplaoded data in Nrrd format, readable by ITK IO factory
  • they updated the Nrrd reader with spacing via direction vectors
  • need orientation matrix
  • right now adding mask bit (for example) in Nrrd format is hard to propagate into ITK - overhead, has to exist in ITK via the generic interface
