 面向对象的影像分析方法能够充分利用高分辨遥感影像信息,有效提取目标信息。分割尺度的选择是面向对象影像分析方法的核心问题。该文采用样本控制的方法,构建了基于面积和周长的分割对象样本一致性评价因子,针对不同的信息提取目标,提出一种改进的遥感影像面向对象最优分割尺度计算模型,并验证了其优越性。 更多还原

【Abstract】 Research for the optimal segmentation-scale calculation model has a positive significance to improve the accuracy of object-oriented image interpretation.Aiming at information extracting of different targets,using the method of samples-controlling which considering area and perimeter as factors to evaluate consistency between segmented-objects and samples,the quality evaluation function is put forward.This quality evaluation function is an improvement on before,it doesn′t only consider the inter...
