GeodesicErosion

GeodesicErosion[marker, mask]
gives the fixed point of the geodesic erosion of the marker constrained by the mask.

Details and Options Details and Options

GeodesicErosion works with binary, grayscale, and other images.
GeodesicErosion works with 3D as well as 2D images, and also with data arrays of any rank.
GeodesicErosion[marker, mask] effectively starts with marker then repeatedly erodes it, masking with mask until the result no longer changes. For symbolic data, the geodesic erosion is done only once.
GeodesicErosion[marker, mask, n] iterates the erosion process at most n times.
GeodesicErosion 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, GeodesicErosion operates on each of them separately.
GeodesicErosion 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.
