Class MTBImageArithmetics

java.lang.Object

de.unihalle.informatik.MiToBo.math.images.MTBImageArithmetics

public class MTBImageArithmetics
extends Object

This class that provides convenience functions for the ImageArithmetics class. Operations with one input image result in images of the same type!! Operations with two input images result in an image of type of the higher input image precision!! If two input images do not have the same size the resulting image is null. Each operation is elementwise.
