Temporal Selection Queries in Video Databases
نویسندگان
چکیده
The paper is concerned with the effective and efficient processing of temporal selection queries in Video Database and generally Temporal Database Management Systems (TDBMS). Based on both general spatio-temporal retrieval framework ([3]) and recent versions of internal-external Priority Search Trees, we present an optimal in time and space algorithm for the problem that answers certain temporal content queries invoking video functions. We prove the optimality by giving both a new theoretical comparison method based on microanalysis and its experimental verification.

Content-Based Querying
Multimedia Database Systems (MMDS) support rich data types, such as text, images, video, and sound. Queries in MMDSs may refer to the content of the stored multimedia objects. This is called content-based querying. However, manual entry of content descriptions is very difficult and subjective. A better approach is to provide automatic content-based retrieval through image, text, and sound inter...
متن کاملSpatio-Temporal Querying in Video Databases
In this paper a video data model that allows efficient and effective representation and querying of spatio-temporal properties of objects is presented. The data model is focused on the semantic content of video streams. Objects, events, activities performed by objects are main interests of the model. The model supports fuzzy spatial queries including querying spatial relationships between objec...
متن کاملSpatio - Temporal Knowledge Representation and Query Processing in Video Information Systems
The aim of this paper is to present a multi-level index structure for video spatio-temporal databases modeling and a specific SQL language for query processing. The data structure we propose for video spatiotemporal knowledge representation is intended to minimize the disk space necessary for data storing and to efficiently represent the spatial and temporal relationships among the objects in t...
متن کاملFuzzy multi-criteria selection procedures in choosing data source
Technology assessment and selection has a substantial impact on organizations procedures in regards to technology transfer. Technological decisions are usually made by a group of experts, and whereby integrity of these viewpoints to a single decision can be quite complex. Today, operational databases and data warehouses exist to manage and organize data with specific features and henceforth, th...
متن کاملNatural Language Interface on a Video Data Model
Depending on a content-based spatio-temporal video data model, a natural language interface is implemented to query the video data. The queries, which are given as English sentences, are parsed using Link Parser, and the semantic representations of given queries are extracted from their syntactic structures using information extraction techniques. At the last step, the extracted semantic repres...
