Multi-structure manual segmentation
The NifTK segmentation tools only allow the segmentation of one single structure of interest, i.e. background/foreground separation. This is ideal from a simplicitly point of view, but it's not ideal when there is interest in multiple neigbouring structures. For example, the hippocampus and the amygdala are two neighbouring structures of interest which are being manually segmented independently. However, because they interface with each other (they share a boundary), the segmentation of the two structures should be consistent (e.g. if a voxel belongs to hippo then it should not belong to the amygdala).
It would thus be ideal to simultaneously segment multiple structures of interest. A simple implementation of this feature can be seen in ITK-Snap, which uses colour painting to encode the segmentation of multiple labels.
This feature will be of great importance to the DRC.
