Class SymmetricDifference

java.lang.Object

fact.pixelsets.SymmetricDifference

All Implemented Interfaces:

stream.Processor

public class SymmetricDifference
extends Object
implements stream.Processor

This processor gets two pixel sets (A and B) and returns the symmetric difference of sets A and B, denoted A △ B or A ⊖ B, is the set of all objects that are a member of exactly one of A and B (elements which are in one of the sets, but not in both). For instance, for the sets {1,2,3} and {2,3,4} , the symmetric difference set is {1,4} .
