High resolution satellite image sequences are multidimensional signals composed of spatiotemporal patterns associated to numerous and various phenomena. Bayesian methods have been previously proposed in [8] to code the information contained in satellite image sequences in a graph representation using Bayesian methods. Based on such a representation, this paper further presents a supervised lear...

A mathematical model of the spatio-temporal dynamics of a two host, two parasitoid system is presented. There is a coupling of the four species through parasitism of both hosts by one of the parasitoids. The model comprises a system of four reaction-diffusion equations. The underlying system of ordinary differential equations, modelling the host-parasitoid population dynamics, has a unique posi...

Spatio-temporal Cox point process models with a multiplicative structure for the driving random intensity, incorporating covariate information into temporal and spatial components, and with a residual term modelled by a shot-noise process, are considered. Such models are flexible and tractable for statistical analysis, using spatio-temporal versions of intensity and inhomogeneous K-functions, q...

Traditional Spread Transform Dither Modulation (ST-DM) is based on the fixed quantization step size, which does not exploit the features of the video contents. Spatio-temporal masking function represents the visual threshold under which human eyes are usually not sensitive. In this paper, we adopts not only the spatial contrast sensitivity function (CSF), the luminance masking function, the con...

In this paper, a new feature called 3D edge oriented gradient histogram of slide blocks is proposed for human action recognition, based on the idea that the slide area of human body edge can be seen as a spatio-temporal silhouette surface when human performing a certain action in video. This feature is processed by defining dense 3D spatio-temporal slide blocks on the spatio-temporal silhouette...

This paper presents an approach for interaction between a human user and a mental model-based spatio-temporal assistance system based on the definitions for conceptual and inferential cognitive adequacy (cf. Knauff et. al., 1995). The paper introduces work in progress that covers ideas towards a visual interaction language that provides cognitively adequate knowledge representation and interact...
