摘要
将兰氏距离变化检测指标引入NDVI变化检测,来实现土地利用的变化检测.在计算阈值时,对原有的局部阈值分割法进行改进,提出基于标准图像地物分类的局部阈值分割法.对检测结果进行精度评价,证实了该方法的可行性和有效性.
Abstract
Canberra distance change detection index was introduced to detect the changes of NDVI and realize the detection of land covering change.In calculating the threshold value, the original local threshold segmentation was improved.The local threshold segmentation based on the classification of standard image object was proposed.The accuracy of the detection results was evaluated, which proved this method was feasible and effective.
