Land Cover Change Detection Based on Value and Shape Optimized Combination
-
摘要: 分析了几种常见的变化检测算法的鲁棒性,在此基础上提出一种光谱量值和形状优化组合的地表覆盖变化检测方法。以西安市及其周边为研究区域,分析该区域2000~2009年的地表覆盖变化。变化检测的总体精度为92.313%,Kappa系数为0.844,优于其他传统算法。Abstract: We propose a new change detection approach based on value and shape optimized combination by analyzing robustness of several traditional change detection algorithms.It was tested in Xi’an City of Shaanxi Province to analyze land cover change from 2000 to 2009.The overall accuracy and Kappa coefficient of change detection result are 92.313% and 0.844 respectively,which outperform other methods.
