School of Computer Studies, University of Leeds, Leeds, UK. School of Computer Studies, University of Leeds, Leeds, UK. View Profile,The spatio-temporal characteristics of sediment deposition were successfully observed in an experimental quasi-steady turbidity current produced by continuous release of a particle-laden suspension. The produced turbidity current proceeds downstream with a constant front velocity.

Hence, the total number of data points considered in this study is 66 522 ...Periodic pattern mining from spatio-temporal trajectories is to find temporal regularities from these spatio-temporal trajectories, ... and urban planning. However, most existing regional pattern mining methods only focus on temporal continuity, spatial compactness, and a single semantics. Outdated or nonhot regions may be discovered if the ...we propose a Graph and Spatio-temporal Continuity based framework for accident anticipation called GSC, which takes the missing agents into account. Specifically, the proposed GSC maintains the spatio-temporal continuity of missing agents, which are in the occluded spatial state in the process of the graph convolution operation. It emphasizes spatio-temporal continuity and integrates both past and future reasoning for tracked objects. Thus, we name it "Past-and-Future reasoning for Tracking" (PF-Track). Specifically, our method adapts the "tracking by attention" framework and represents tracked instances coherently over time with object queries.In this paper, we propose an uncertainty-based accident anticipation model with spatio-temporal relational learning. It sequentially predicts the probability of traffic accident occurrence with dashcam videos. Specifically, we propose to take advantage of graph convolution and recurrent networks for relational feature learning, and leverage ...Missing data reconstruction is a critical step in the analysis and mining of spatio-temporal data; however, few studies comprehensively consider missing data patterns, sample selection and spatio-temporal relationships. As a result, traditional methods often fail to obtain satisfactory accuracy or address high levels of complexity. To combat these problems, this study developed an effective ...Spatio-Temporal Information Exploitation. Exploita-tion of spatial and temporal information is a core problem in object tracking field. Existing trackers can be divided into two classes: spatial-only ones and spatio-temporal ones. Most of offline Siamese trackers [2,26,25,60,29] be-long to the spatial-only ones, which consider the objectSubsequently, spatio-temporal remote-sensing images are processed using phase normalization, which is to reduce the time phase difference of image data and enhance the complementarity of information. The multi-scale image information is then decomposed using the L₀ gradient minimization model, and the non-redundant information is processed by ...end with an accident in temporal context. It can be recurrently learned by updating historical memory with agent-specific features and the spatial relational representation. To address the variability of the spatio-temporal relational representations, a probabilistic module is incorporated to simultaneously predict accident scoresSpatial–temporal reasoning is an area of artificial intelligence that draws from the fields of computer science, cognitive science, and cognitive psychology.

Spatio-temporal continuity is a common requirement of different applications [13]. However, the quality requirements differ across fields. For example, land surface models need a SM product with ...As driving is a continuous process, the curve of temporal change of velocity should show a sort of continuity and smoothness. But the traditional map matching method doesn’t consider the connection among the trajectory points and can probably break the continuity. The true velocity information can be undermined by the map matching method.characteristic of spatio-temporal continuity (STC). STIP [9] and iDT [10] are good video descriptors. They depend on the optical flow or trajectories to exploit the video continuity, while they also need much computational cost.

Spatio-temporal patterns appear almost everywhere in nature, and their description and understanding still raise important and basic questions. However, if one looks back 20 or 30 years, definite progress has been made in the modeling of insta bilities, analysis of the dynamics in their vicinity, pattern formation and stability, quantitative ...All spatio-temporal samples corresponding to one condition were averaged. The SD and SEM were updated during the averaging process. Given the continuity of V1, the neuronal and BOLD response to the two stimuli should be approximately symmetrical across the border between them. The mean spatio-temporal BOLD response to condition 2 was spatially ...Continuity editing is an editing system used to maintain consistency of both time and space in the film. Continuity editing helps ground audiences in the reality of the film while establishing a clear and structured narrative. The goal of continuity editing is to make the mechanisms of filmmaking invisible as to help the audience dismiss ...
In our framework, graphs are constructed specifically for encoding the spatial and temporal dependencies among the different facial identities. Therefore, the GNN can leverage this graph structure and model the temporal continuity in speech as well as the long-term spatial-temporal context, while requiring low memory and computation.
