                         language, whose vocabulary is composed of dilations, erosions, 
                         complementation, union and intersection. They are called 
                         morphological operators when expressed in this form. Translation 
                         invariant and locally defined set operators are called 
                         W-operators. Decision diagrams have been used as an alternative

                         paper shows that the reduced and ordered binary decision diagram

                         corresponding morphological operator. This procedure of computing 
                         decision diagrams can be applied to the automatic proof of 
                         equivalence between morphological operators, since the W-operator
