Special Topic R Wrapping

Users Current Usage and Impressions

• Use ITK for Registration and Segmentation
• Loading Time Series from FMRI
  • loading in a vector image is ok, or a series of images

Current Problems

• There are no dashboard machines contributing R builds
• R Packaging does not work with Latest requiring documentation fields
• Automatic Testing is currently not working
• Generated tests are out of date
• SWIG support for R is primitive
• Does R support Objects with methods?
  • Should we only expose the procedural methods?
  • S3 S4 Level objets?
• R does not appear to have namespaces. Should methods and object be prefixed with sitk?
  • R now requires packages in namespaces
  • name spaces have been available for a while

Features Needs for Native Feel

• Packaging
• Documentation
• Support for conversion to native arrays
• Use native arrays instead of wrapped std::vectors
• print, show methods

Organization and Planning

• JIRA is needed to communicate what people are working on and issues being address.
  • Create R Label
• Need to improve documentation for new developers and add setup script for development environment
• One suggested approach
  • Separate the building of the SimpelITK and the Wrapping of the interface
  • May be possible to do the wrapping the the cran style, and just depend on SimpleITK library

Outstanding Test Failures

• Voting Binary - patch for ITK in gerrit
• CSharp.ExampleSimpleGaussian - now compiling and running, needs a base line image
• BasicFilters.ThresholdMaximumCC - Failing due to horrible programming practices in test template, needs revision and cleanup
• VectorConnectedComponent - Failing due to numeric tolerances, need a more tolerant input image

Other Open Topics

• Wiki and Doxygen pages should be review for release.
• Release delayed until ITK 4.1rc1 is tagged
• Adding support for import and export vector images to numpy
• Registration
  • to be major new feature to work on in Febuary
• C++ installation

Schedule

• Discuss long term goals and milestones.

• Documentations

• Automate Script to List filters wrapped
  • This script should take as input a list of ITK Modules or Directories, for each modual determine which filters are implemented in SimpleITK
  • Additional input would include filter/files to exclude
  • Output could be a dox file, so that it could be a doxygen related page

• Registration is very important
