Description: Let X be the subset of Zn that corresponds to the input image in, and let k be the value of the parameter connex (that is, 4, 8 (2d) or 6, 26 (3d)), which is the connectivity chosen for X.

The border B(X) of X is defined by: B(X) = {x in X, (Gamma_nk(x) inter Xbar) not empty} where nk is the complementary connectivity for k.
