Mixed-state spatio-temporal auto-models
We consider in this paper a general modelling for mixed-state data. Such data consist of two components of different types: the observations record many zeros, together with continuous real values. They occur in many application fields, like rainfall measures, or motion analysis from image sequences. The aim of this work is to present ad hoc spatio-temporal models for these kinds of data. We pr...
متن کاملSpatio-Temporal Models For Sustainability
Many applications that aim at enhancing sustainability rely on some sort of spatio-temporal model. The task can be monitoring or prediction in traffic networks, power grids, building energy management, river flow volume, and sea level – to mention just a few. The positive effect on the environment is achieved by a better control, better planning of processes or better disaster management. Spati...
متن کاملSpatio-Temporal Convolutional Sparse Auto-Encoder for Sequence Classification
We address in this paper the problem of task-independent video sequence classification. We aim to introduce a generic model which differ from the highly problem-dependent dominant methodology that relies on so-called hand-crafted features. We propose a learning-based model with two main steps: the first one aims to automatically learn spatio-temporal features instead of hand-crafting them. Thes...
متن کاملSpatio-temporal Background Models for Outdoor Surveillance
Video surveillance in outdoor areas is hampered by consistent background motion which defeats systems that use motion to identify intruders. While algorithms exist for masking out regions with motion, a better approach is to develop a statistical model of the typical dynamic video appearance. This allows the detection of potential intruders even in front of trees and grass waving in the wind, w...
متن کاملLearning spatio-temporal models of facial expressions
The human face is used to regulate the conversation by gazing or nodding, to interpret what has been said by lip reading, and to communicate and understand somebody’s affective state and intentions on the basis of the shown facial expression. Machine understanding of human facial behavior could revolutionize human-machine interaction technologies and fields as diverse as security, behavioral sc...
