Retrieval of Similar Layouts

This paper is about how to retrieve similar CAD (-like) layout drawings. Such a drawing consists of up to a hundred objects, each with semantic and geometric attributes. In the joint venture FABEL, we are exploring seven approaches to interpret this information, some focusing on semantics, others on geometry. Each retrieval method compares its interpretation of a given drawing with those in a library and returns one or more similar drawings. Retrieval methods can be combined both sequentially and in parallel, depending on their properties. We propose a scenario for combining our retrieval methods.
