GeodesicErosion

GeodesicErosion

gives the fixed point of the geodesic erosion of the image marker constrained by the image mask.

MORE INFORMATION

GeodesicErosion works with binary, grayscale, and other images.

GeodesicErosion effectively starts with marker, then repeatedly erodes it, masking with mask, until the result no longer changes.

GeodesicErosion iterates the erosion process at most n times.

GeodesicErosion by default treats all eight pixels surrounding a given pixel as adjacent.

The option setting CornerNeighbors->False treats only the four pixels in the coordinate directions as adjacent.

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.
