New Issues

Working on Multi-Input Filters

  • Completed and in next

Update On Transformations for Registration

  • Dan?

Gradient ImageFilter

  • I have a modified ITK, which enable GradientImageFilter to work with VectorImages
  • Getting GradientRecursiveGaussian working is going to be more complicated

PyBuffer Issues

  • Support for old python buffer interface?
    • With numpy 1.5 it appears that we are unable to get a PEP 3118 Buffer interface


Valgrind failures

  • Both Valgrind and VS10 debug are reporting failures on the same test.
  • Real bug here must be addressed.

Shared libraries on Windows

  • Need to add the ITK library directory to the PATH environmental variable to correctly load dlls.

User Requested Features

  • A couple of post on the users list related to better support for VectorImages or 4D images. Reading, accessing buffer and pixel and converting to numpy.
  • A users wanting to use the edge potential image filter, there is not way to create gradient image. Nor compose scalar images into a vector image.

Priorities for next release

  • Registration
  • C++ installation
  • Splitting Wrapping directory into languages
  • Splitting BasicFilters Library
  • improved vector image support


  • Discuss long term goals and milestones.
  • Documentations
  • Registration is very important
