The SimpleITK bindings are already capable of doing:

* R Packaging does not work with Latest requiring documentation fields

* Generated tests are out of date
so we're well on the way.
* SWIG support for R is primitive
* Does R support Objects with methods?
The other neat thing I'd like is operator overloading. R has
** Should we only expose the procedural methods?
facilities for that, so that you should be able to write expressions
** S3 S4 Level objets?
which treat images just like any other variable.1
* 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

Links

Release 0.4.0

  • Currently 53 binary downloads
  • Topics to be merged into release?
    • SIMPLEITK-239_AddingSetupForDevelopment
    • SIMPLEITK-245_ImageJ64ForMac??

Priorities for next release

  • Registration
  • C++ installation
  • Splitting BasicFilters Library
  • improved vector image support

R Wrapping Follow-up

  • working on fixing the automatic testing for R
  • Richard Beare is hacking away he is reporting the following:
I'm thinking about import options based on my old R imaging package.
Images were also represented by a pointer to a C object (external
reference). By providing the right generic operators we could treat
the image as an array for purposes of subsetting. This meant that you
could do something like this:

im2 <- im1[100:200,]  # im2 is another image, not an array, with all
the columns and rows 100 to 200

If we wanted an array version of an image we'd do

im2 <- as.array(im1)

as.array is a generic R operation that we specialised for images.

The SimpleITK bindings are already capable of doing:

pixval <- im1[c(100,200)]

so we're well on the way.

The other neat thing I'd like is operator overloading. R has
facilities for that, so that you should be able to write expressions
which treat images just like any other variable.1

Outstanding Test Failures


Other Open Topics

  • Wiki and Doxygen pages should be review for release.
  • 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
