Created page with 'Back to Winter project week 2015 Agenda =Introduction= * Purpose: Discuss present and future of Segmentation object support * Time: Tuesday 3…'

New page

[[2015_Winter_Project_Week#Agenda|Back to Winter project week 2015 Agenda]]

=Introduction=
* Purpose: Discuss present and future of Segmentation object support
* Time: Tuesday 3:15 - 4:00
* Participants: Csaba Pinter, Andriy Fedorov, Steve Pieper, Jc, Andras Lasso (via skype) and everybody who is interested

=Agenda=
* Present latest plans and progress regarding Segmentation object support (Csaba) (slides)
** GUI and features
** Architecture
** Design questions, issues, and future work
* Labelmap node class - integration to Slicer core
* Discussion on the features and implementation details
* Come to an agreement
** Features and architecture
** Integration
** Tentative roadmap

		+	=Notes=
		+	* Important use cases
		+	** Huge number of segments (Bill, Brad, etc.)
		+	*** Issue: efficient storage and processing
		+	*** Fire segment-specific events from segmentation node (with segment ID)
		+	*** Load subsets of data based on spatial constraints in an on-demand fashion
		+	**** Need to support geometrical decision functions by default (contain, overlap, etc.), maybe even on the CLI level
		+	*** Storage of at the moment non-displayed segments in a compressed way?
		+	** Tractography (Nicole): ask Alex or Lauren
		+	** SceneViews
		+	*** They are defined by display node on/off states basically
		+	* Relevant existing implementations / interfaces
		+	** Similar notions in ITK as the proposed labelmap types: LabelImage ~ LabelMap, LabelMap ~ RLE (ImageStencil)
		+	** VTK6 color table additions
		+	** vtkCompositeDataset, vtkMultiBlockDataset: both composite objects already defined in VTK
		+	* Design alternatives
		+	** vtkSegment subclass of vtkDataObject or vtkCompositeDataset or vtkMultiBlockDataset
		+	** Explicit ID for segments: need to uniquely identify segments
		+	*** Segmentation vector index not good because of its non-unique nature (remove, etc.) (Jim)
		+	*** Tags are one option but not too explicit
		+	*** Need to unambiguosly link segment to color table
		+	** Color, opacity stored elsewhere than the segment
		+	*** Color information is needed to be stored at at least two locations (segment, color table of merged labelmap, ?)
		+	*** Display node? Segment could still store a "default" color (Andras)
		+	** Volume reference in segmentation could be FrameOfReferenceUID (transforms would need to support that anyway; ensuring equality is the most important so UID is just as good for this as matrices or something else)
		+	** Extending CLI to be able to tell the desired representation will be necessary (Jim)
		+	*** Similar to existing ContourSelectorWidget?
		+	* Encoding antology (hierarchies, colors, groupings) is important (Nicole, Andrey)
		+	** Tags can be used, or something more explicit, need ideas
		+	* Other ideas
		+	** Compute/show estimated data loss of conversion
