| 摘 要： | Zernike矩因具有正交性和旋转不变性而广泛应用于模式识别、图像分析等领域.Pseudo-Zernike 矩具有与Zernike 矩相似的性质,但它较Zernike 矩具有更好的抗噪声性.由于pseudo-Zernike矩的复杂性,相关的快速算法的研究尚未得到很好的解决.本文根据pseudo-Zernike矩自身的特点,推导了一种快速有效的计算方法.

| 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. |
