gives the fixed point of the geodesic dilation of the marker constrained by the mask.

Details and OptionsDetails and Options

  • GeodesicDilation works with binary, grayscale, and multichannel images, operating on each channel separately.
  • GeodesicDilation works with 3D as well as 2D images, and also with data arrays of any rank.
  • GeodesicDilation[marker,mask] effectively starts with marker then repeatedly dilates it, masking with mask until the result no longer changes. For symbolic data, the geodesic dilation is done only once.
  • GeodesicDilation[marker,mask,n] iterates the dilation process at most n times.
  • GeodesicDilation effectively performs a morphological reconstruction by dilation.
  • The following options can be given:
  • CornerNeighborsTruewhether to include corner neighbors
    PaddingNonepadding method to use
  • The default setting Padding->None considers smaller neighborhoods at the edges of an image.
