Abstract:

A framework in which information about images’s form and information about images’s content are addressed in a principled way is proposed so as to solve the image retrieval problems of uncertain background knowledge. The framework can deal with the semantic information with various levels of confidence. A two level model consistent of form and content is proposed to represent images, an uncertainty description logic called UALC is proposed to deal with the semantic information with uncertainty, the task of images retrieval is thus reduced to logical reasoning in UALC, a reasoning algorithm of UALC is given finally.

Key words: image retrieval, description logic, uncertainty reasoning
