“…In recent years, there have been many multimedia query language proposals [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16], which can be classified into three categories: entirely new and specialized languages [1][2][3][4], languages based on logic or functional programming approach [5,6], and languages that are extensions of SQL [7][8][9][10][11][12][13][14][15][16]. One problem with a brand new multimedia query language is the lack of acceptance by users.…”

We propose a unified multimedia query language called UMQL, based on a semi-structured data model. In contrast to previous multimedia query languages that are either designed only for one particular medium or not powerful enough on multimedia query ability, UMQL is a general and powerful multimedia language which can support effectively queries based on content, structure, spatial relationships and temporal relationships of multimedia data, and finally has been shown to be very expressive and quite suitable for multimedia information retrieval.

“…One is keyword-based and the other is based on visual content. Kuo and Chen [12] proposed a content-based video query language (CVQL) in which objects appearing in video data, as well as temporal and spatial relationship among objects, can be specified. But, it is not easy for user to specify queries relating events.…”

Content-based video retrieval is one of the most challenging areas of research in information sciences. Here we present a new method for efficient indexing, storage and retrieval of echocardiogram video data. The architecture and implementation details of the system have been discussed. A hierarchical state based indexing scheme has been used for faster retrieval of information related to states of objects present in echo video. In video segmentation phase, views as well as states and sub-states of objects in a video are identified. Accordingly, schemas are populated. An object-relational database approach has been adopted to store object information into a backend RDBMS. The proposed video query language can be used to compose queries based on video contents using annotations, states, events, spatial or temporal relations. For ease of specifying query, a user friendly interface has been provided. Retrieved segments can be played back one at a time in a separate window.

“…Although querying video databases is a newer concept, there have been several studies on querying the content of videos [1,8,11,12,13,15,16,17,18,19,20]. There exist mainly two different approaches for content-based query processing in video systems.…”

Abstract: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 objects and querying the trajectories of objects. The model is flexible enough to define new spatial relationship types between objects without changing the basic data model. A prototype of the proposed model has been implemented. The prototype allows various spatio-temporal queries along with the fuzzy ones and it is prone to implement compound queries without major changes in the data model.
