摘要

遥感影像中的空间对象及其边界具有模糊性。针对遥感影像中模糊对象的表现特征，借助云理论和云模型来对模糊对象进行表达研究。基于影像的灰度和梯度等数字特征，构建基于数字图像的对象云，用对象云表达模糊对象，核外半云环表达其边界，从而用模糊数学的方法来合理表达遥感影像模糊对象，最后以遥感影像为例进行验证。该方法不仅丰富和完善了云理论，同时也为模糊对象表达，遥感影像的理解和分析提供了一种新的思路。

Abstract

The spatial object and its edge in the RS image possess fuzzy character. Based on the features of fuzzy objects in the image and the cloud theory

the paper studies the representation of fuzzy objects in image. By the gray and gradient or other digital characters of the image

we can construct a spatial object cloud. The fuzzy spatial object can be represented by the object cloud. The edge of the spatial object can be represented by half cloud ring. So fuzzy objects in the RS image can be represented based on the fuzzy mathematics cloud model properly. Experimental results show that the method is both efficient and effective. It enriches the cloud theory

and proposes a new idea for the representation of the fuzzy object and image comprehending and analyzing

especially the remote sensing image.
