| 摘 要： | 本文从面向对象的遥感信息提取中的尺度效应研究入手,对影像对象的分形维数、紧凑度、面积、均值、标准差和与邻域均值差分等特征进行了实验.在此基础上,根据"类内同质性大,类问异质性大"的最佳分类原则,提出了面向对象的RMAS方法,该方法的思想是,当对象RMAS值最大时,对象内部的异质性最小,对象外部的异质性最大,此时的分割尺...

| Abstract: | From scale effect problem in the remote sensing information extraction,the targets'fractal dimensions,compact ratio,areas,mean value,standard deviation and mean differential to neighbors of image objects were experimental researched in the paper.It found that these index values of all targets would fluctuate with scales,and different targets in the images have different feature values and scales.It is necessary to extract the region of interest in optimal scale images.In view of this,RMAS method was develop... |
