An Algebra for Moving Objects
نویسنده
چکیده
Qualitative representing and reasoning for road network moving objects is an important problem in spatio-temporal reasoning, but it is till open. We propose a new spatial algebra for road network moving objects based on Interval Algebra Theory. Renz has developed an algebra DIA to represent one dimensional moving objects by giving time interval a spatial interpretation. We extend DIA to road network, propose RNDIA. We give an algebra formalization for RNDIA compatible to DIA. Then the reasoning problems such as RSAT are primarily discussed. Our work proposes an executable qualitative representation and reasoning method of road network moving object. * Corresponding author.

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 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 ...

Qualitative representing and reasoning for road network moving objects are key works to put spatiotemporal reasoning into practices, but those are still open problems.

متن کاملA Novel Method for Tracking Moving Objects using Block-Based Similarity
Extracting and tracking active objects are two major issues in surveillance and monitoring applications such as nuclear reactors, mine security, and traffic controllers. In this paper, a block-based similarity algorithm is proposed in order to detect and track objects in the successive frames. We define similarity and cost functions based on the features of the blocks, leading to less computati...
