openlifu.seg.skinseg.create_closed_surface_from_labelmap

openlifu.seg.skinseg.create_closed_surface_from_labelmap(binary_labelmap: vtkImageData, decimation_factor: float = 0.0, smoothing_factor: float = 0.5) → vtkPolyData[source]

Create a surface mesh vtkPolyData from a binary labelmap vtkImageData.

Parameters:

  • binary_labelmap – input vtkImageData binary labelmap

  • decimation_factor – 0.0 for no decimation, 1.0 for maximum reduction.

  • smoothing_factor – 0.0 for no smoothing, 1.0 for maximum smoothing.

Returns:

the resulting surface mesh

Return type:

vtkPolyData

The algorithm here is based on the labelmap-to-closed-surface algorithm in 3D Slicer: https://github.com/Slicer/Slicer/blob/677932127c73a6c78654d4afd9458a655a4eef63/Libs/vtkSegmentationCore/vtkBinaryLabelmapToClosedSurfaceConversionRule.cxx#L246-L476
