ITK/Release 4 Planning

Wish List

Oriented Images

• Support ND oriented images
  • Using anything other than 3D images won't compile
• Support ND image in N+1 dimension
  • 2D image can have an origin specified in 3D, thus a series of 2D images is not always Z-aligned
• All images are oriented - remove concept of an un-oriented image
• Check use of orientation throughout ITK
  • Spatial Objects
  • Meshes

Image Representation

• Allow the use of strides that are not equal to the image width
  • Would ease the collaboration of ITK with opencv
  • Would allow the use of sse operations
  • Might be redundant with correct use of image regions

Statistics

• Complete statistics refactoring (see NAMIC sandbox)

FEM Meshes

• Consolidate FEM Meshes and ITK Meshes

Image Registration

• Set up the infrastructure to ease the implementation of modern optimization schemes for image registration
  • Requires Hessian or pseudo-Hessians of the cost function
  • Requires several types of update rules (additive, compositional, inverse compositional, etc.)
