| Abstract(in English) | Similarity retrieval technology,which,from image databases, enables users to retrieve images that have similar contents to the retrieval key,becomes an essential technology as image databases grows to very large ones.This paper deals with cloud in satellite imagery,and builds a similarity retrieval system based on the similarities of shape and spatial distribution of cloud regions. First the shape of a cloud region is represented using shape decomposition by affine-related polygons;then the decomposition result is structured into an attributed relational graph.This formulation naturally defines the similarity measure as graph matching cost.Moreover,the system tries to learn human subjective evaluation by adjusting weighting factors associated with graph matching cost.All the methods are formulated based on optimization principle. |
