correlation energy

[‚kär·ə′lā·shən ‚en·ər·jē]

(atomic physics)

The difference between the experimentally measured energy of a particular energy level of an atom or molecule and the energy calculated in the Hartree-Fock approximation.

(solid-state physics)

The modification of the Coulomb energy of a crystal that results from the tendency of electrons to stay apart from each other.

The minimum average correlation energy (MACE) filters [25] are one of such design and show good results in the field of automatic target recognition and applications in biometric verification [14, 26].

Conventional MACE filter [25] minimizes the average correlation energy of the reference images while constraining the correlation output at the origin to a specific value (usually 1), for each of the reference images.

Just like conventional MACE filter, UMACE filter also minimizes the average correlation energy of the reference images and maximizes the correlation output at the origin.
