Detailed Description

produce sampled points from a segmented image

vtkLabeledImagePointSampler is a utility filter that produces points from a labeled input 3D volume or 2D xy image. This can be used to reduce the overall size of the data, and/or convert data (from a segmented image to a sampled vtkPointSet) for filters like vtkVoronoiFlower2D/3D or vtkGeneralizedSurfaceNets3D that require input points. The required input image data is a integer region id point data array (i.e., the labels). (The filter is akin to dividing cubes, which is a way to represent contours with point clouds.) The output of the filter is represented by the vtkPointSet subclass vtkPolyData containing a list of points, and a point data array identifying the region from which each point is generated.

The filter produces points in an adaptive manner, more dense near segmented region boundaries, and less dense moving away from region boundaries. The process of adaption can be controlled by specifying either a linear density distribution, choosing every Nth point, or an exponential distribution, with power N (e.g., point density reduced as a power of 2).

Segmented regions within the input image are identified by specifying a set of one or more values/labels. Points not in any defined (labeled) regions are called background points. As expected, labeled points are generated from the input set of voxel/pixel labels. Background points can be given a "BackgroundPointLabel" which can be used by other filters for thresholding, or for generating tessellations (e.g., Voronoi filters). (By default, the BackgroundPointLabel is a large negative integral number.) By default, both labeled and background points are output; optionally, only points within labeled or background regions can be output.

In some applications, it may be advantageous to randomly joggle (alternatively: perturb, jitter, jiggle) the generated output points. Because a image is being sampled, it can produce regularly spaced points that can affect the performance and numerical stability of certain filters like Voronoi and Delaunay.

Note: The term "joggle" was first used in the context of Voronoi degeneracies by the popular QuickHull algorithm (and the associated QHull implementation qhull.org).

Warning: If the input labels (region ids) are not of type int, they will be converted to type int. This is because several important filters (e.g., vtkVoronoiFlower2D, vtkVoronoi3D, vtkGeneralizedSurfaceNets2D) currently require int region labels as input. This could be extended using templates at the cost of significant bloat, as long as the representational types support both negative and positive values (e.g., unsigned will not work correctly).; This filter can produce large numbers of points. It is recommended that the filter parameter N and density distribution function is chosen carefully to manage the size of the output.; This class has been threaded with vtkSMPTools. Using TBB or other non-sequential type (set in the CMake variable VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly.

◆ SetBackgroundPointMapping()

virtual void vtkLabeledImagePointSampler::SetBackgroundPointMapping ( int )

virtual

These methods are used to control how output region labels are assigned to background points.

When BackgroundPointMapping is enabled, points with region labels not in the input list of segmented values are assigned the BackgroundPointLabel. By default, BackgroundPointMapping is off, so the input image labels are used. If however, BackgroundPointMapping is on, then the BackgroundPointLabel is assigned to unlabeled points. (Recall that background points have input labels/values that do not exist in the specified set of labels/values). By default, the BackgroundPointLabel is set to a negative integral number that typically denotes the point is outside of the segmented points. (Make sure that the background pt id is not a value in the set of labels/values or havoc may ensue).

virtual

Modifiy the probability of the point randomization process.

The range should be within [0,1], and it's effect is to clamp the minimum and maximum selection probabilities. By default, the range is (0,1).
