An Indexing and Searching Structure for Multimedia Database Systems
نویسندگان
چکیده
In this paper, we present a database searching structure that incorporates image processing techniques to model multimedia data. A Simultaneous Partition and Class Parameter Estimation (SPCPE) algorithm that considers the problem of video frame segmentation as a joint estimation of the partition and class parameter variables has been developed and implemented to identify objects and their corresponding spatial relations. Based on the obtained object information, a web spatial model (WSM) is constructed. A WSM is a multimedia database searching structure to model the temporal and spatial relations of semantic objects so that multimedia database queries related to the objects' temporal and spatial relations on the images or video frames can be answered eeciently.

MUMIS – A Multimedia Indexing and Searching Environment
We describe in this paper the MUMIS Project (Multimedia Indexing and Searching Environment)1 and show the role linguistically motivated annotations, coupled with domain-specific information, can play for the indexing and the searching of multimedia (and multilingual) data. MUMIS develops and integrates base technologies, demonstrated within a laboratory prototype, to support automated multimedi...
متن کاملOptimised Kd-tree Indexing of Multimedia Data
Near neighbor searching in image databases is a multidimensional problem. The kd-tree is one of the first methods proposed for indexing multidimensional data. We describe optimizations of this method, and determine when they are appropriate. We discuss adaptations of the tree to feature extraction and indexing problems in multimedia data. Results show increased functionality and speed using the...
