GeodesicDilation[marker, mask]
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 other images.
- 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.
- GeodesicDilation by default treats all pixels surrounding a given pixel as adjacent. A given pixel has eight adjacent pixels in 2D and 26 adjacent pixels in 3D.
- The option setting CornerNeighbors->False treats only the pixels in the coordinate directions as adjacent, which would include four pixels in 2D and six pixels in 3D.
- If multiple image channels are present, GeodesicDilation operates on each of them separately.
- GeodesicDilation takes a Padding option that specifies the values to assume for pixels outside the image.
- The default setting Padding->None considers smaller neighborhoods at the edges of an image.
