A 3D OBJECT RETRIEVAL SYSTEM USING TEXT AND SIMPLE VISUAL INFORMATION

3D objects are being increasingly produced and used by a broad public. Tools are thus required to manage collections of 3D objects in a similar way to the management of image collections including the possibility to search using text queries. The system we are presenting in this paper goes one step further allowing to search for 3D objects not only using text queries but also using very simple similarity metrics inferred from the 3D spatial description. The multimodal search is stepwise. First, the user searches for a set of relevant objects using a classical text–based query engine. Second, the user selects a subset of the returned objects to perform a new query in the database according to a relevance feedback method. The relevance is computed using different geometric criteria that can be activated or deactivated. External objects can also be submitted directly for a similarity query. The current visual features are very simple but are planned to be extended in the future.
