Abstract
We introduce the circular harmonic wavelet matched filter, that uses the wavelet transform in improve the performance of the rotation invariant circular harmonic filters in terms of the peak sharpness and the robustness to noise. In the optical implementation, the wavelet bandpass filter guarantees the full range rotation invariance of the filter by eliminating the circular subsampling error.
