1.There are two primary methods for spatial component extraction: principal component analysis(PCA) and intention-hue-saturation(IHS) transform. PCA method transforms the multispectral image into several noncorrelated and independent components and the first component(PC-1) represents the spatial component of the original multispectral image. IHS method transforms only three bands of the original multispectral image into three components of intention,hue and saturation.
提取空间分量的基本方法有两种:主成分分析(PCA)和IHS变换法,PCA法可以对多光谱图像的所有波段进行分析,得到的第一主成分PC-1代表原始多光谱图像的空间信息,而IHS法只能输入多光谱图像的3个波段,经IHS变换得到的I分量代表原图像的空间信息;收藏指正
