基于复数矩不变性的遥感边缘信息提取

The Remote Sensing Edge Information Extraction Based on Complex Moment Invariance

通过引入四元数的方法,对多光谱遥感影像进行整体统一的处理,经过求解影像的色彩中心值来完成影像的分割,从而达到对影像进行边缘提取,以及自动提取出影像中面状特征的目的。本文主要提取面状水域,试验结果表明,该方法能对多光谱遥感影像中的水域提取效果相较传统做法有很大的提高。

In this paper,based on the quaternion method,integrating the multi-spectral remote sensing image,and through solving the color centers,the image was split.Consequently,the purposes of the edge-detection of image and the automatic extraction of the area-shape features were achieved.The results show the effect of water extraction of the multispectral remote sensing image has greatly improved by using this method,compared with the traditional practice.
