They cannot be put into the context of a simple union of erosions with morphologi-
cal structuring elements. This is because erosion by a structuring element in mor-
phology is basically a foreground operation. Either the structuring element fits the

Minimization and implementation of a nonincreasing function from Fig. 5.4. There
is no problem with terms X 0 X 1 and X 1 X 2 that can be implemented as simple morphology.
However, term X 1 X 2 must be implemented as a hit-or-miss transform.
