| 摘 要： | 提出了利用遥感影像分割获取像斑进行变化检测的方法。构造了像斑差熵作为衡量变化的指标,选取一定数目训练样本,利用目标函数法找到最佳阈值,并同相关系数法进行了比较。实验结果显示像斑差熵更适用于遥感影像变化检测。

| Abstract: | This paper proposed a complete change detection method,which uses the segments obtained from the image segmentation.An entropy difference is constructed and the threshold is calculated by the object function through selecting some training samples.Using the entropy difference compared with the correlation coefficient method,it shows that the entropy difference is more suitable for the remote sensing image change detection. |
