基于状态转移矩阵的变化检测方法

Research of change detection using state transition matrix

土地利用变化检测一直是遥感影像变化检测研究的重点。在分析已有变化检测方法的基础上提出了一种基于状态转移矩阵(State Transition Matrix,STM)的变化检测方法。以像斑为分析单位,通过样本像斑的选择与更新对变化检测区域进行分析,利用辅助数据生成的地物变化状态转移矩阵对变化检测结果进行修正。实验证明了该方法的有效性。

Land-use has been the focus of the study in the remote sensing image change detection.This paper proposes a change detection method based on the State Transition Matrix（STM）.It uses segments as the unit to analyse the images.After the samples selection and update,the STM, obtained from the auxiliary data, is used to amend the result of the change detection.The experiment shows the effectiveness of the method.
