Abstract
We propose a new kind of filter, it is the complex conjugate of the Fourier transform of the circular harmonic phase component. Our theoretical analysis verify that this kind of filter is fully rotational invariant. The computer simulation results show that this kind of filter yields a much higher correlation peak, a better discrimination ability and a higher signal-to-noise ratio compared with the traditional circular harmonic filter.
