چکیده

A model for computing image ow in image sequences containing a very wide range of instantaneous ows is proposed. This model integrates the spatio-temporal image derivatives from multiple temporal scales to provide both reliable and accurate instantaneous ow estimates. The integration employs robust regression and automatic scale weighting in a generalized brightness constancy framework. In addition to instantaneous ow estimation the model supports recovery of dense estimates of image acceleration and can be readily combined with parameterized ow and acceleration models. A demonstration of performance on image sequences of typical human actions taken with a high frame-rate camera, is given.

New Multiscale Models and Self-Similarity in Tropical Convection

One of the unexplained striking features of tropical convection is the observed statistical self-similarity, in clusters, superclusters, and intraseasonal oscillations through complex multi-scale processes ranging from the mesoscales to the equatorial synoptic scales to the intraseasonal/planetary scales. Here new multi-spatial scale, multi-time scale, simplified asymptotic models are derived s...

A new 2D block ordering system for wavelet-based multi-resolution up-scaling

A complete and accurate analysis of the complex spatial structure of heterogeneous hydrocarbon reservoirs requires detailed geological models, i.e. fine resolution models. Due to the high computational cost of simulating such models, single resolution up-scaling techniques are commonly used to reduce the volume of the simulated models at the expense of losing the precision. Several multi-scale ...

Temporal Changes of Effective Discharge for Suspended Sediments Transport in Korkorsar Watershed

Suspended sediment transport by rivers is important in water quality of cities and villages fed by certain drainage basins. On the other hand, the effective discharge refers to discharge that transports the most sediment over long time and controls the shape of river bed. Therefore, determination of effective discharge for suspended sediment transport and analysis the variation of effective dis...

Large-eddy simulation of turbulent flow over an array of wall-mounted cubes submerged in an emulated atmospheric boundary-layer

Turbulent flow over an array of wall-mounted cubic obstacles has been numerically investigated using large-eddy simulation. The simulations have been performed using high-performance computations with local cluster systems. The array of cubes are fully submerged in a simulated deep rough-wall atmospheric boundary-layer with high turbulence intensity characteristics of environmental turbulent fl...

The quadrants' boundary intensity discontinuity a result of of the video-camera consisting of four separate A/D banks. As a result, ow estimation at the quadrant boundaries is inaccurate. The problem could be overcome by local gain compensation. The dense ow algorithms of Black and Anandan 6] is used. The algorithm's parameters were changed to achieve best measurement results. The same eeect co...
