混合像元线性分解的精度估算

Accuracy Estimation of Mixed Pixel Linear Decomposition

遥感图像中普遍存在着混合像元,对混合像元进行分解是遥感图像处理中的难点。混合像元线性分解技术是进行高光谱影像处理的常用方法。本文针对混合像元线性分解的基本原理与算法作了简要分析,并通过实验的方法估算了混合像元线性分解模型的精度。

The mixed pixel exists in remote sensing images commonly and the decomposition of mixed pixel is difficult during the processing of remote sensing images.Linear mixed pixel decomposition technique is a commonly used method for hyperspectral image processing.This paper briefly analyzed the basic principles and algorithms of the mixed pixel linear decomposition,and estimated the accuracy of linear mixed pixel decomposition model based on the experiments.
