摘要
矩和矩不变量在图像处理和模式识别领域有广泛的应用.首先介绍灰度图像矩和彩色图像四元数矩的定义,然后详细介绍矩的不变量构造方法以及矩的快速计算方法,目的是给相关领域的学者提供一个较全面的视角.
Moments and moment invariants have been extensively used in the fields of image analysis and pattern recognition.We first recall the definition of traditonal moments for grey-level image and the quaternion moments for color image.Then we review the ways to construct the moment invariants and the computation aspect of moments.The aim of this paper is to provide an overview on this topic.
