JPSearch – An emerging standard for image search and retrieval

The problem of organization of multimedia information for annotation, search and retrieval of such content in a fashion similar to the way it is done for text today, has been a focus of interest in the scientific and technical communities over the past two decades. The MPEG-7 standard was a first step towards this goal, by proposing a common syntax to describe multimedia content either with low-level or high-level features and metadata. JPEG committee has initiated a new work item called JPSearch to take this effort one step further for applications involving images. In a first stage, JPSearch has defined a framework and an underlying architecture which allow a wide range of image search and retrieval applications to be mapped to them. In a second stage, various elements of this structure for which standardization is desired have been identified. These include import, export and exchange of ontologies, sub-ontologies, and ontology elements, a common query language with a set of precise input parameters to specify search criteria for search and retrieval over one or more local or distributed image repositories, a common specification language to allow users/systems to describe the aggregated return result sets for user presentation or machine consumption, the circulation without any information loss of metadata among image management devices and platforms, such as metadata creation/update devices and image repositories, and re-use of metadata. JPSearch is currently working towards finalization of its first part which includes the framework and architecture definition, and has initiated several new parts where international standards will soon be defined. This seminar will present an overview of these efforts and a look into the workplan of JPSearch.
