Anomaly behaviour detection based on the meta-Morisita index for large scale spatio-temporal data set

open access: yesJournal of Big Data, 2018
In this paper, we propose a framework for processing and analysing large-scale spatio-temporal data that uses a battery of machine learning methods based on a meta-data representation of point patterns.

Enhancing Spatio-Temporal Identity: States of Existence and Presence

open access: yesISPRS International Journal of Geo-Information, 2016
This work presents a new approach that aims to characterize the spatio-temporal relationships that exist between geographical objects that are absent or non-existent at the moment of analysis.

Spatio-temporal Analysis of Unstained Cells In-vitro [PDF]

open access: yes, 2009
The tracking of individual cells in time-lapse microscopy facilitates the assessment of certain characteristics of different cell types. Since manual tracking of an adequate number of cells over a considerable number of frames is tedious and sometimes not feasible, there is a vital interest in automated methods.

Spatio-temporal aggregation for visual analysis of movements [PDF]

open access: yes2008 IEEE Symposium on Visual Analytics Science and Technology, 2008
Data about movements of various objects are collected in growing amounts by means of current tracking technologies. Traditional approaches to visualization and interactive exploration of movement data cannot cope with data of such sizes. In this research paper we investigate the ways of using aggregation for visual analysis of movement data.

Spatio-temporal analysis for parameterizing animated lines [PDF]

open access: yesProceedings of the ACM SIGGRAPH/Eurographics Symposium on Non-Photorealistic Animation and Rendering, 2011
We describe a method to parameterize lines generated from animated 3D models in the context of animated line drawings. Cartoons and mechanical illustrations are popular subjects of non-photorealistic drawings and are often generated from 3D models.

A Method for Visualizing Independent Spatio-Temporal Patterns of Brain Activity

open access: yesEURASIP Journal on Advances in Signal Processing, 2009
Evoked and coordinated brain signals often exhibit distinct, individualized spatial and temporal characteristics, such as amplitude and phase couplings across and within spatial channels.
