  • Very fast connected components labeling (Union-find algorithm)
  • MaxTree-based connected operators
    • Attribute openings: Area, Volume, Height, Bounding-Box
    • Regional maxima dynamics
    • Marker propagation
  • Most operators work for binary and gray-scale images
  • Image (2D arrays), volume or sequence processing  (3D arrays) and signal processing (1D arrays)
  • Support for structuring elements in decomposed form (faster algorithms)
  • Planar and non-planar structuring elements
  • Images represented in byte, short and signed integer data types
  • Fast queue-based algorithms for distance transform, watershed, morphological reconstruction, labeling, area-opening, etc.
  • Fast binary operations using intrinsic 32 bit parallel operations available in 32 bit machines

Main classes of operators

  • Gray-scale Dilation & Erosion 
  • Morphological Filters: opening, closing, alternating sequential filters 
  • Connected Operators: watershed, open and close by reconstruction, labeling, regional maxima and minima, alternating sequential filters by reconstruction, area opening, h-dome and h-basin 
  • Distance Transforms including geodesic  
  • Residues: gradient, contour, top-hat 
  • Hit-Miss: skeletonization, skiz
  • Watershed: gray-scale from markers. Based on gradient or similarity
