Estimating the result size of a query to velocity skewed moving objects
نویسندگان
چکیده
With new developments in positioning systems and electronics, various researches for moving objects have progressed [3,5,6]. Our paper is related to selection queries considering future positions of moving objects, which are referred to as future queries [5]. An example of the future query is as follows: “which airplanes will be inside a query window 20 minutes from now?” Airplanes correspond to moving objects that move as time passes. Recently, a data model that can deal with the future locations of an object has been proposed [5]. Like various studies [2,4,6], our work is based on this model.

Statistical Background Modeling Based on Velocity and Orientation of Moving Objects
Background modeling is an important step in moving object detection and tracking. In this paper, we propose a new statistical approach in which, a sequence of frames are selected according to velocity and direction of some moving objects and then an initial background is modeled, based on the detection of gray pixel's value changes. To have used this sequence of frames, no estimator or distribu...
متن کاملBoosting Moving Object Indexing through Velocity Partitioning
There have been intense research interests in moving object indexing in the past decade. However, existing work did not exploit the important property of skewed velocity distributions. In many real world scenarios, objects travel predominantly along only a few directions. Examples include vehicles on road networks, flights, people walking on the streets, etc. The search space for a query is hea...
متن کاملPredicted Range Aggregate Processing in Spatio-temporal Databases
Predicted range aggregate (PRA) query is an important researching issue in spatio-temporal databases. Recent studies have developed two major classes of PRA query methods: (1) accurate approaches, which search the common moving objects indexes to obtain an accurate result; and (2) estimate methods, which utilize approximate techniques to estimate the result with an acceptable error. In this pap...
متن کاملExtending the Qualitative Trajectory Calculus Based on the Concept of Accessibility of Moving Objects in the Paths
Qualitative spatial representation and reasoning are among the important capabilities in intelligent geospatial information system development. Although a large contribution to the study of moving objects has been attributed to the quantitative use and analysis of data, such calculations are ineffective when there is little inaccurate data on position and geometry or when explicitly explaining ...
متن کاملMoving Objects Tracking Using Statistical Models
Object detection plays an important role in successfulness of a wide range of applications that involve images as input data. In this paper we have presented a new approach for background modeling by nonconsecutive frames differencing. Direction and velocity of moving objects have been extracted in order to get an appropriate sequence of frames to perform frame subtraction. Stationary parts of ...
