SoGeodesicPropagationProcessing2dengine For an introduction to geodesy, see section Geodesy Principle.
The result of the
SoGeodesicPropagationProcessing2d Command, applied to a binary image without holes, is a grey level image where each pixel has a grey level value equal to . The following image contains the result of a geodesic propagation on an image to differentiate the various grey level values appearing as stripes or rings. For the largest particle, has a minimum of 36 and then values spread until 70 at the extremities. It means that the shortest distance is 36 and the length of the particle can be considered as equal to 70. For particles close to a disk, the geodesic center is located at the center of the particle, and points with the same grey level value are concentric rings.
The geodesic function has a minimum for each particle which is either a point or a region, named the geodesic center of the particle. The value of this minimum is named the geodesic radius of the particle, as a circle drawn from any of the geodesic center points with such a radius will hit the extremities of the particle.
The maximum is reached at points usually located at the extremities of the particles named geodesic extremities. The value of this maximum is named the geodesic diameter and is seldom equal to 2 times the geodesic radius. In the case of a disk, the center is the geodesic center and the diameter is the geodesic diameter.
