摘要
通过研究四元数在彩色影像上应用的优势,提出了一种基于四元数的彩色遥感影像水域提取的算法。实验表明,该算法具有明显的优越性和适应性,对卫星影像海岸水沿线的提取具有指导意义。
Feature extraction is an important step in image targets recognition. This paper analyses the applications of quatemion in color image processing, and thus puts forward the arithmetic of RS color image waters feature extraction based on quatemion. The result of experiment indicates that the arithmetic has obvious advantage and adaptability.
