New Issues

Update On Transformations for Registration

• Dan?

Gradient ImageFilter

• Specifically we don't have a gradient image filter. ITK uses CovariantVectors which are very problematic to convert to VectorImages.

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

Dashboard

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

Schedule

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