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.
