Improving Zernike Moments Comparison for Optimal Similarity and Rotation Angle Retrieval

Abstract

Zernike moments constitute a powerful shape descriptor in terms of robustness and description capability. However the classical way of comparing two Zernike descriptors only takes into account the magnitude of the moments and loses the phase information. The novelty of our approach is to take advantage of the phase information in the comparison process… (More)
