Circular-harmonic minimum average correlation energy filter for color pattern recognition.
Minimum average correlation energy filtering is applied to rotation-invariant color pattern recognition. A method of derivation of the circular-harmonic component minimum average correlation energy filter for an arbitrary order is introduced. This filter has the advantage of being useful for several color channels simultaneously. Both computer simulations and optical experiments are presented, proving the discrimination abilities for this implementation.
