摘要
针对传统的基于像元变化检测方法在高分辨遥感影像变化检测中的缺陷,在对比现有变化检测方法的基础上提出一种基于马尔可夫模型的变化检测方法。以影像图斑为分析单元,通过选择样本图斑,并对变化检测区域进行分析,计算变化模糊矩阵,最后引入地物变化状态转移矩阵进行变化判别,实验结果表明该方法检测精度较高。
As traditional change detection method is restricted to high-resolution remote sensing image,we use a change detection method based on Markov Chain through comparing existing traditional methods.It uses segments as the unit,selecting sample segments,and analysis the changing area.Then calculate s the change fuzzy matrix,and finally decides the change segments based on the state transition matrix.The result of the experiment proves this method's high accuracy.
