• 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

• VS9 failing for 64-bits and on window 8 32 bits
• Configuration error on RH5.7 for java
  • http://www.cdash.org/CDash/testDetails.php?test=134368000&build=1987166

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
