mmtop - Top of a set.

Synopsis
f = mmtop( A )
Input
A: Binary image (logical uint8).
Output
f: Gray-scale uint8 image.
Description
The top of a set is the function with values equal to the top of the set (upper values). It is the inverse of the subgraph.
Limitation
This implementation is restricted to 1-D gray scale functions.
Examples 
f=[3 0 5 4 5 2 3 1 4];
sg=mmsg(f,6)

sg =
     0     0     0     0     0     0     0     0     0
     0     0     1     0     1     0     0     0     0
     0     0     1     1     1     0     0     0     1
