The two-dimensional (2D) and three-dimensional (3D) orthogonal moments are useful tools for 2D and 3D object recognition and image analysis. However, the problem of computation of orthogonal moments has not been well solved because there exist few algorithms that can efficiently reduce the computati

Orthogonal moments have been successfully used in the ΓΏeld of pattern recognition and image analysis. However, the direct computation of orthogonal moments is very expensive. In this paper, we present two new algorithms for fast computing the two-dimensional (2D) Legendre moments. The ΓΏrst algorithm
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,
