چکیده
The paper is an investigation into different notions of spatial, temporal, and spatio-temporal continuity. A formal framework is proposed in which a number of different notions of continuity is situated.

Qualitative Spatio-Temporal Continuity
We explore different intuitive notions of spatio-temporal continuity and give a formal characterization of continuity for space-time histories. We investigate the types of transitions possible for the RCC-8 topological relations under each distinct notion of spatio-temporal continuity and provide a hierarchy of conceptual neighbourhood diagrams.
متن کاملSTCS-GAF: Spatio-Temporal Compressive Sensing in Wireless Sensor Networks- A GAF-Based Approach
Routing and data aggregation are two important techniques for reducing communication cost of wireless sensor networks (WSNs). To minimize communication cost, routing methods can be merged with data aggregation techniques. Compressive sensing (CS) is one of the effective techniques for aggregating network data, which can reduce the cost of communication by reducing the amount of routed data to t...
متن کاملThe Objective and Implementation of Dynamic Visualization of Spatio-temporal Geographical Processes
The Spatio-temporal data is the description of the time, space, and attribute information of the geographic spatiotemporal process, which reflects the spatio-temporal process information of geographical phenomenon changing with the time on the earth-surface space. The spatio-temporal process information is complex and changing. Thus according to the objective of dynamic visualization of geograp...
متن کاملA New Wavelet Based Spatio-temporal Method for Magnification of Subtle Motions in Video
Video magnification is a computational procedure to reveal subtle variations during video frames that are invisible to the naked eye. A new spatio-temporal method which makes use of connectivity based mapping of the wavelet sub-bands is introduced here for exaggerating of small motions during video frames. In this method, firstly the wavelet transformed frames are mapped to connectivity space a...
متن کاملAbducing Qualitative Spatio-Temporal Histories from Partial Observations
We present a logic-based framework in which a qualitative spatio-temporal world model is constructed from local surveys i.e. partial spatio-temporal knowledge. Complete space-time histories are obtained through an abductive process driven by continuity constraints and a library of possibly domain specific behaviour patterns. The abduction technique is circumscription, which implements the heuri...
