Multi Label Segmentation

Using multiple segmentations with the Segmentation bundle

#!wiki caution
This is really just a sketch. Move / change anything

Following a proposal of Sebastian Ordas to support multi-label segmentations, this page will be used to sketch future changes to the Segmentation bundle and the related framework.

Shortcomings of the current implementation

• 8-bit images are used for segmentations by default, wasting 7 of 8 byts, occupying far more memory than technically necessary

Wishlist

• what is not possible or cumbersome and should be changed?
• what enhancements would help in which situations?
• to support multi-label images, ITK's label object classes (http://www.insight-journal.org/browse/publication/176) could be useful
  • how does I/O work?
  • do we need a new data type for MITK (derived from BaseData?)
  • how could these be mapped types for rendering?

Implications on the implementation

• what parts of MITK would need to be changed?
• what needs to be changed in the Segmentation view?
