Detailed Description

This class encapsulates a segmentation that can contain multiple segments and multiple representations for each segment.

The primary purpose of this class is to serve as a container to store the segments (in labelmap analogy the "labels"). Also provides generic functions on the segmentation level. Performs conversion to a specified representation, extracts geometry information etc.

Main points to remember:

◆ AddEmptySegment()

std::string vtkSegmentation::AddEmptySegment ( std::string  segmentId = "",
std::string  segmentName = "",
double  color[3] = NULL 
)

Add empty segment containing empty instances of the contained representations

Parameters
segmentIdID of added segment. If empty then a default ID will be generated
See also
GenerateUniqueSegmentId
Parameters
segmentNamename of added segment. If empty then the segmentId will be used as name.
colorof added segment. If not specified then empty then vtkSegment::SEGMENT_COLOR_INVALID is used.
Returns
ID of the added segment. Empty on failure

◆ AddSegment()

bool vtkSegmentation::AddSegment ( vtkSegment segment,
std::string  segmentId = "",
std::string  insertBeforeSegmentId = "" 
)

Add a segment to this segmentation, do necessary conversions, and observe underlying data for changes. Necessary conversions:

  1. If the segment can be added (
    See also
    CanAcceptSegment), and it does not contain the master representation, then the master representation is converted using the cheapest available path.
  2. Make sure that the segment contains the same types of representations that are present in the existing segments of the segmentation (because we expect all segments in a segmentation to contain the same types of representations).
    Parameters
    segmentthe segment to observe
    insertBeforeSegmentIdif specified then the segment is inserted before insertBeforeSegmentId
    Returns
    Success flag

◆ ApplyLinearTransform()

virtual void vtkSegmentation::ApplyLinearTransform ( vtkAbstractTransform *  transform)
virtual

Apply a linear transform on the master representation of the segments. The others will be invalidated Harden transform if poly data, apply to directions if oriented image data.

◆ ApplyNonLinearTransform()

virtual void vtkSegmentation::ApplyNonLinearTransform ( vtkAbstractTransform *  transform)
virtual

Apply a non-linear transform on the master representation of the segments. The others will be invalidated Harden transform both if oriented image data and poly data.

◆ CanAcceptRepresentation()

bool vtkSegmentation::CanAcceptRepresentation ( std::string  representationName)

Determine if the segmentation is ready to accept a certain type of representation by copy/move or import. It can accept a representation if it is the master representation of this segment or it is possible to convert to master representation (or the segmentation is empty).

◆ CanAcceptSegment()

bool vtkSegmentation::CanAcceptSegment ( vtkSegment segment)

Determine if the segmentation is ready to accept a certain segment. It can accept a segment if it contains a representation that is acceptable, or if it is empty.

◆ ContainsRepresentation()

bool vtkSegmentation::ContainsRepresentation ( std::string  representationName)

Determine if segments contain a certain representation type Note: This assumes the first segment contains the same type of representations as all segments (this should be the case by design)

◆ ConvertSegmentUsingPath()

bool vtkSegmentation::ConvertSegmentUsingPath ( vtkSegment segment,
vtkSegmentationConverter::ConversionPathType  path,
bool  overwriteExisting = false 
)
protected

Convert given segment along a specified path

Parameters
segmentSegment to convert
pathPath to do the conversion along
overwriteExistingIf true then do each conversion step regardless the target representation exists. If false then skip those conversion steps that would overwrite existing representation
Returns
Success flag

◆ ConvertSingleSegment()

bool vtkSegmentation::ConvertSingleSegment ( std::string  segmentId,
std::string  targetRepresentationName 
)
protected

Converts a single segment to a representation.

◆ CopyConversionParameters()

virtual void vtkSegmentation::CopyConversionParameters ( vtkSegmentation aSegmentation)
virtual

◆ CopySegmentFromSegmentation()

bool vtkSegmentation::CopySegmentFromSegmentation ( vtkSegmentation fromSegmentation,
std::string  segmentId,
bool  removeFromSource = false 
)

Copy segment from one segmentation to this one

Parameters
fromSegmentationSource segmentation
segmentIdID of segment to copy
removeFromSourceIf true, then delete segment from source segmentation after copying. Default value is false.
Returns
Success flag

◆ CreateRepresentation() [1/2]

bool vtkSegmentation::CreateRepresentation ( const std::string &  targetRepresentationName,
bool  alwaysConvert = false 
)

Create a representation in all segments, using the conversion path with the lowest cost. The stored conversion parameters are used (which are the defaults if not changed by the user). Conversion starts from the master representation. If a representation along the path already exists then no conversion is performed. Note: The conversion functions are not in vtkSegmentationConverter, because they need to know about the master representation which is segmentation- specific, and also to allow optimizations (steps before per-segment conversion).

Parameters
targetRepresentationNameName of the representation to create
alwaysConvertIf true, then conversion takes place even if target representation exists. False by default.
Returns
true on success

◆ CreateRepresentation() [2/2]

bool vtkSegmentation::CreateRepresentation ( vtkSegmentationConverter::ConversionPathType  path,
vtkSegmentationConverterRule::ConversionParameterListType  parameters 
)

Generate or update a representation in all segments, using the specified conversion path and parameters. Conversion starts from the master representation, and all representations along the path get overwritten.

virtual

Deep copy one segmentation into another.
