Paper Abstract

The spatial region in RS image has positional and thematic values uncertainties. Based on the uncertainties and the cloud theory, the paper studies the representation of spatial uncertain region in image and proposes a new method applied to spatial uncertain region representation based on cloud model. In 2-dimensional universe of discourse, by the gray and gradient or other digital characters of image, we can construct object-cloud of spatial object. Uncertain spatial region can be represented by object-cloud. Edge of spatial object can be represented by half-cloud-ring. So spatial uncertain region can be represented based on cloud model properly. Experiments testify that the method is both efficient and effective. It enriches the cloud theory, and proposes a new idea for representation of fuzzy object and image comprehending and analyzing, especially remote sensing image.
