System and method to dynamically display the related messages in short messages

Abstract: This invention relates to system and method to dynamically display the related messages in short messages. It is applied in a handheld data processing equipment. It comprises a multimedia database, a keyword-recognizing module, a keyword-searching module, and a correlation-prompting module. The multimedia database stores several multimedia data, the keyword-recognizing module can list a table of the preset keywords, and recognize the contents of the short messages at the local site and the remote site, so as to generate the keyword information. The keyword-searching module searches the corresponding multimedia data in the multimedia database according to the keyword information. Finally, the correlation-prompting module generates the prompt of the correlation data, and display it in the hand-held data-processing device.

Methods and apparatus for processing ranked fuzzy cartesian queries

Abstract: Ranked fuzzy cartesian queries request top-K composite objects in a multimedia database. These composite objects, comprising multiple simple objects with their relations specified, are ranked by a fuzzy AND score of individual object properties and their fuzzy relations. Ranked fuzzy cartesian queries appeared in many different applications but were not fully exploited because of high computational complexity. In accordance with the present invention, methods and apparatus are provided for preprocessing a ranked fuzzy cartesian query to prune candidates which will not appear in the final top-K composite objects. Algorithms for processing queries against two simple objects and against three or more simple objects are separately described. These algorithms use a bound-and-prune technique to determine the candidates which can be removed from the search space. Disclosed methods are guaranteed to have no false dismissal.

NAMIBIE, an interface dedicated to multimedia access to coastal data and information for Integrated Coastal Zone Management processes

Abstract: NAMIBIE (a french acronym for Integrated Multimedia Navigator Within Coastal Environment Data Bases) is a specific tool which first concept has been established by Ifremer and has been developped by an association between research in the field of coastal environment, innovation in the field of new information and communication technologies and services in the field of coastal integrated management and impact studies. The objectives of this tool are to facilitate research, direct access and display of relevant multimedia coastal integrated data and information according to an interactive, widely opened and playfull interface. The principles are based upon the fact that sustainable decision making needs an optimized unterstanding of coastal processes and better consultation between actors. In this purpose the development of the tool has considered that the end-user should and could be free to look after the data and the information he needs for a particular site or environment of interest and for a specific ICZM question according to easy navigation interfaces. That is why NAMIBIE concept is based upon : - a coherent 3D representation of the coasts (i.e. from catchement areas to continental shelf and deep sea), which considers a coherent DEM from land to sea and textural representation of the environment using satellite imagery textural displays, - a 3D navigator which allows the user to fly or dive over and within the coastal environment of interest, - a multimedia database (text, graphs, image, maps, geographic objects, modelling results...) specific to the territory of interest, - an interactive interface which helps in finding relevant information associated to specific questions. The technologies used include VRML data format, integration of standard GIS format (shp, grid, img) within the navigator, integration and display of modelling data. The production chain is realized in C++ and Java scripts allow dialogue between web pages and 3D windows...

A Multimedia Database Application for Vehicle Surveillance System

Abstract: Vehicles surveillance system provide a large range of informational services for the driver and administrator such as multi view road and driver surveillance videos from multiple cameras mounted on the vehicle, video shots highlighting the traffic conditions on the roads and monitoring driving behavior. Annotation and retrieving of these video streams has an importance role on visual aids for safety and vehicle guidance. Using video as a primary multimedia data source requires effective ways of retrieving the desired video data from a database. To do so, a model that classifies vehicle video data on the basis of traffic information and its semantic properties which were described by driver's eye gaze direction was developed in this paper. Then the annotated video data based on the model is organized and streamed by retrieval platform and adaptive streaming method. The experimental results show that this model is a good example for evidence-based traffic instruction programs.
