【Abstract】 Zernike moments are widely used in the fields of pattern recognition and image analysis due to their good properties such as orthogonality and rotation invariance.Pseudo-Zernike moments have similar properties as those of Zernike moments;moreover,they are less sensitive to image noise than the conventional Zernike moments.However,the problem of fast computation of pseudo-Zernike moments has not been well solved due to the complexity of the pseudo-Zernile polynomials.In this paper,we present a novel method for fast computing the pseudo-Zernike moments.更多还原
