摘要
本文提出了一种直接利用角点坐标计算形状的矩的方法 ,并导出了低阶矩的闭合形式 ,最后给出了计算M K Hu提出的七个矩不变量的算法。该算法计算的是经典不变矩的精确值 。
This paper proposes a method which computes the moments of a shape using only its corner pixels, and derives the closed form of lower order moments. Finally, an algorithm for computing the moment invariants proposed by M K Hu is presented This algorithm computes the same set of moment invariants, but reduces computations tremendously
