Sampling Trajectory Streams with Spatiotemporal Criteria
- Proceedings of SSDBM
, 2006
"... Monitoring movement of high-dimensional points is essential for environmental databases, geospatial applications, and biodiversity informatics as it reveals crucial information about data evolution, provenance detection, pattern matching etc. Despite recent research interest on processing continuous ..."

continuous queries in the context of spatiotemporal data streams, the main focus is on managing the current location of numerous moving objects. In this paper, we turn our attention onto a historical perspective of movement and examine trajectories generated by streaming positional updates. The key challenge
Efficient Anomaly Monitoring Over Moving Object Trajectory Streams
"... Lately there exist increasing demands for online abnormality monitoring over trajectory streams, which are obtained from moving object tracking devices. This problem is challenging due to the requirement of high speed data processing within limited space cost. In this paper, we present a novel frame ..."

A Paraperspective Factorization Method for Shape and Motion Recovery
, 1997
"... The factorization method, first developed by Tomasi and Kanade, recovers both the shape of an object and its motion from a sequence of images, using many images and tracking many feature points to obtain highly redundant feature position information. The method robustly processes the feature traject ..."

trajectory information using singular value decomposition (SVD), taking advantage of the linear algebraic properties of orthographic projection. However, an orthographic formulation limits the range of motions the method can accommodate. Paraperspective projection, first introduced by Ohta, is a projection
Managing Trajectories of Moving Objects as Data Streams
"... The advent of modern monitoring applications, such as location-based services, presents several new challenges when dealing with continuously evolving spatiotemporal information. Frequent updates in the positions of moving objects, unexpected fluctuations in data volume and the requirement for real- ..."
Abstract

-time responses to continuous spatiotemporal queries indicate the limitations of traditional database systems. We attempt to model management of moving objects with the underlying assumption that their trajectories are essentially continuous, timevarying and possibly unbounded data streams. We propose a basic
Event detection and analysis from video streams
- IEEE Transactions on Pattern Analysis and Machine Intelligence
, 2001
"... AbstractÐWe present a system which takes as input a video stream obtained from an airborne moving platform and produces an analysis of the behavior of the moving objects in the scene. To achieve this functionality, our system relies on two modular blocks. The first one detects and tracks moving regi ..."

A Framework of Traveling Companion Discovery on Trajectory Data Streams
"... The advance of mobile technologies leads to huge volumes of spatio-temporal data collected in the form of trajectory data stream. In this study, we investigate the problem of discovering object groups that travel together (i.e., traveling companions) from trajectory data streams. Such technique has ..."

FACIAL NERVE STREAM TRAJECTORY DATA MODELLING AND VISUALIZATION
"... Abstract—Bell’s palsy is the paralysis of facial muscles caused by perturbations affecting the facial nerve. It is the origin of a physical suffering, and has an emotional and psychological impact on patients. Treatments of Bell’s palsy are still not well-defined, nevertheless physical therapies tec ..."

The developmental trajectory of nonadjacent dependency learning
- Paper presented at the 14th Biennial International Conference on Infant Studies
, 2004
"... We investigated the developmental trajectory of nonadjacent dependency learning in an artificial language. Infants were exposed to 1 of 2 artificial languages with utter-ances of the form [aXc or bXd] (Grammar 1) or [aXd or bXc] (Grammar 2). In both languages, the grammaticality of an utterance depe ..."
