de.unihalle.informatik.MiToBo.core.datatypes.MTBStructuringElement

@ALDParametrizedClass
public class MTBStructuringElement
extends Object

class representing a 2D flat (, i.e. without different gray values) structuring element
for the use with morphological operations
values are stored in a rectangular 2D array (rows: 1st dimension, columns: 2nd dimension)
whereas onValue represents set locations and 0 represents unset locations
