To support the retrieval, fusion and discovery of visual/multimedia information, a spatial query language for multiple data sources is needed. In this paper we describe a spatial query language interpreter which is based upon the a-operator sequence and in practice expressible in an SQL-like syntax. The algorithm for the a-query translator is explored in detail. The implementation of the algorithm including data structures, pseudo-codes and source codes in C is presented. Query examples handled successfully by the a-query implementation are als ....etc

Abstract
The ability to accurately track hand movement provides new opportunities for human computer interaction (HCI). Many of todayâ„¢s commercial hand tracking devices based on gloves can be cumbersome and expensive. An approach that avoids these problems is to use computer vision to capture hand motion. In this paper, we present a complete real-time hand tracking and 3-D modeling system based on a single camera. In our system, we extract feature points from a video stream of a hand to control a virtual hand model with 2-D global motio ....etc

LOCATION BASED SPATIAL QUERY PROCESSING IN WIRELESS BROADCAST ENVIRONMENTS-MOBILE COMPUTING

Abstract: Location-based spatial queries (LBSQ s) refer to spatial queries whose answers rely on the location of the inquirer. Efficient processing of LBSQ s is of critical importance with the ever-increasing deployment and use of mobile technologies. We show that LBSQ s has certain unique characteristics that the traditional spatial query processing in centralized databases does not address. For example, a significant challenge is presented by wirel ....etc

Spatial &Temporal Compression of Streaming Video for Digital TV Broadcast
Digital TV has come of age in India. It affords extremely good picture quality and stunning theatre-like sound effects. Besides, it offers a tremendous amount of user interactivity, something which is not possible in TVs using analog technologies such as NTSC/ PAL/ SECAM. With interactive TV, it is possible to perform on-line trading, conduct secure bank transactions, surf the internet, request viewing of selected programs, and perform airline/ ....etc
