Analysis of spatiotemporal patterns in a model of olfaction
Neurocomputing, 2004Abstract We model spatiotemporal patterns in locust olfaction with the dynamic neural filter, a recurrent network that produces spatiotemporal patterns in reaction to sets of constant inputs. We specify, within the model, inputs corresponding to different odors and different concentrations of the same odor.

Eigenvectors and eigenfunctions in spatiotemporal EEG analysis
Brain Topography, 1989As a supplement to the article "An Eigenfunction Approach to the Inverse Problem of EEG" by Hjorth and Rodin in Brain Topography, 1988, 1 (2): 79-86, this paper discusses in greater detail the interrelations between the concepts of EEG sample vector, eigenvalue and eigenvector.

Spatiotemporal visual analysis of human actions
2010In this dissertation we propose four methods for the recognition of human activities. In all four of them, the representation of the activities is based on spatiotemporal features that are automatically detected at areas where there is a significant amount of independent motion, that is, motion that is due to ongoing activities in the scene. We propose

Proceedings of International Conference on Image Processing, 2002
It has been shown that motion can be characterized in the spatiotemporal-frequency (Fourier) domain, and that this phenomenon can be exploited for the computation of optical flow. However in practical (natural) sequences, the signatures of the different motions cannot be resolved in the Fourier domain, nor associated with their respective regions in ...

1997 IEEE International Conference on Systems, Man, and Cybernetics. Computational Cybernetics and Simulation, 2002
In this paper, we consider the use of spatiotemporal/spatiotemporal-frequency (st/stf) representations (an extension of time-frequency representations) for dynamic scene analysis. The joint nature of these representations, which provide frequency information localized to points in spacetime, provides a very natural framework for simultaneous spatial ...
