摘要：

We present numerical and experimental results for a rotation-invariant pattern recognition method using a joint transform correlator. The reference image input to the correlator along with the input scene is a circular harmonic function. This positive real function is derived from a phase only circular harmonic matched filter for the reference image and is shown to give good discrimination for translation and rotation-invariant pattern recognition.
