Hausdorff distance

(definition)

Definition: A measure of the resemblance of two (fixed) sets of geometric points P and Q, defined as H(P,Q)=max{max_{a∈ P} min_{b∈ Q} d(a,b), max_{a∈ Q} min_{b∈ P} d(a,b)} where d(·,·) is the distance metric, usually the Euclidean distance.

Note: Adapted from [AS98, page 437].
