Abstract

New distortion-invariant correlation filters for reconnaissance applications (rotation-invariance) are considered. These use circular harmonic functions (CHFs) combined with minimum average correlation plane (MACE) filter techniques and new generalized rotation-invariant MACE filters using symmetry requirements.
