Detailed Description

Filter that computes surface normals for contour edge points.

Takes a set of contour surfaces (represented as vtkPolygon-based mitk::Surface objects) and computes normal vectors for each contour edge point. The computed normals can be accessed on the output surfaces via:

filter->GetOutput(i)->GetVtkPolyData()->GetCellData()->GetNormals();

If a segmentation binary image is provided via SetSegmentationBinaryImage(), the filter ensures that the computed normals point away from (not into) the segmented region.

Reset()

void mitk::ComputeContourSetNormalsFilter::Reset

(

)

Reset the filter by removing all inputs and outputs.

SetMaxSpacing()

void mitk::ComputeContourSetNormalsFilter::SetMaxSpacing

(

double

maxSpacing

)

Set the maximum voxel spacing of the original image.

Used to determine the sampling distance for normal computation.

Parameters

[in]

maxSpacing

The maximum spacing value.

SetProgressStepSize()

void mitk::ComputeContourSetNormalsFilter::SetProgressStepSize

(

unsigned int

stepSize

)

Set the step size by which the progress bar advances per contour.

Parameters

[in]

stepSize

The progress increment per processed contour.

SetSegmentationBinaryImage()

void mitk::ComputeContourSetNormalsFilter::SetSegmentationBinaryImage ( mitk::Image *  segmentationImage )

inline

Set the segmentation binary image for normal direction validation.

When set, the filter checks that computed normals point outward (away from the segmented region) and flips them if necessary.

Parameters

[in]

segmentationImage

Pointer to the binary segmentation image.

SetUseProgressBar()

void mitk::ComputeContourSetNormalsFilter::SetUseProgressBar

(

bool

status

)

Enable or disable the MITK progress bar during computation.

Parameters

[in]

status

True to use the progress bar, false to disable it.
