| 摘 要： | 特征提取是影像目标分类识别的重要步骤。通过研究四元数在多光谱遥感影像处理中应用的优势,提出了一种基于四元数的多光谱遥感影像水域提取的算法。该算法把多光谱遥感影像的所有波段作为一个整体考虑,充分利用了光谱信息,同时也减少了计算量。实验表明,该算法具有明显的优越性和适应性。

| Abstract: | Feature extraction is an important step in image targets recognition.This paper analyses the applications of quaternion in multispectral RS image processing,and thus puts forward the arithmetic of multispectral RS image waters feature extraction based on quaternion.This arithmetic regards all warebands of the multispectral RS image as a whole.It fully uses spectral information,and reduces the amount of computation.The result of experiment indicates that the arithmetic has obvious advantage and adaptability. |
