introduction water vapor is an essential climate element. through latent heat exchanges, the water vapor is considered as the principal way of energy transport through the global atmosphere and it is also a dominant greenhouse gas (held and soden, 2000). over the oceans, warmer surface temperatures may lead to increased evaporation and, therefore, greater specific humidity, but an approximately...

Disease-specific understanding of echocardiographic sequences requires accurate characterization of spatio-temporal motion patterns. In this paper we present a method of automatic extraction and matching of spatio-temporal patterns from cardiac echo videos. Specifically, we extract cardiac regions (chambers and walls) using a variation of multiscale normalized cuts that combines motion estimate...

In this paper, a novel structure is proposed for human activity modeling using time sequential spatio-temporal texture primitives. Gabor filters, which are proven to be robust 2D texture representation tools, are extended to 3D domain to capture spatio-temporal texture features. A well known filtering algorithm and an unsupervised clustering algorithm, the Genetic Chromodynamics, are combined t...

The spatio temporal variations of seismicity preceding Uttarkashi, 1991 and Chamoli, 1999 earthquakes were studied based on the data during period 1981 to 2000 using catalogues prepared by India Meteorological Department. Two scenarios examined. In one case epicentral distance from respective impending worked out for all recorded a ten years prior earthquake Uttarkashi Chamoli respectively. oth...

We present a spatiotemporal analysis of a statistically stationary rotating-turbulence experiment, aiming to extract a signature of inertial waves and to determine the scales and frequencies at which they can be detected. The analysis uses two-point spatial correlations of the temporal Fourier transform of velocity fields obtained from time-resolved stereoscopic particle image velocimetry measu...
