Constructor Details
- ChamferDistanceTransform3DShort
  
  public ChamferDistanceTransform3DShort(ChamferMask3D mask)
  
  Creates a new algorithm for computing 3D distance maps based on a chamfer mask.
  
  Parameters:
  
  mask - the chamfer mask to use for propagating distances
- ChamferDistanceTransform3DShort
  
  public ChamferDistanceTransform3DShort(ChamferMask3D mask, boolean normalize)
  
  Creates a new algorithm for computing 3D distance maps based on a chamfer mask.
  
  Parameters:
  
  mask - the chamfer mask to use for propagating distances
  
  normalize - whether distance map should be normalized by the weight associated to orthogonal shifts
Method Details
- mask
  
  public ChamferMask3D mask()
  
  Specified by:
  
  mask in interface ChamferDistanceTransform3D
  
  Returns:
  
  the chamfer mask used by this distance transform algorithm.
- distanceMap
  
  public ij.ImageStack distanceMap(ij.ImageStack image)
  
  Computes the distance map from a 3D binary image. Distance is computed for each foreground (white) pixel, as the chamfer distance to the nearest background (black) pixel.
  Specified by:
  
  distanceMap in interface DistanceTransform3D
  
  Parameters:
  
  image - a 3D binary image with white pixels (255) as foreground
  
  Returns:
  
  a new 3D image containing:
  
  0 for each background pixel
  
  the distance to the nearest background pixel otherwise
