Zernike moments (ZMs) have been successfully used in pattern recognition and image analysis due to their good properties of orthogonality and rotation invariance. However, their computation by a direct method is too expensive, which limits the application of ZMs. In this paper, we present a novel al
This paper presents a new algorithm for fast and accurate computation of Legendre moments. For a binary image, by use of a Green's theorem, we transform a surface integral to a simple integration along the boundary. The inter-order relationship of Legendre moments is then investigated. As a result,
Moment invariants are important shape descriptors in computer vision. The method of decomposing the trigonometric function is suggested to obtain various moment invariants. Based on this method, the "multi-ΓΏlter" algorithm is introduced as an ecient way to generate large numbers of moment invariants
