Aiming at classic Mean Shift based on tracking algorithm can not track target when the speed changed, the paper proposed an improved algorithm based on corrected background weighted histogram(CBWH), the algorithm used two iterations on target, first time used mean shift to iterate and calculated the similarity coefficient, second iteration used twice the current frame center minus the previous frame...
As a widely used groundwater flow model, MODFLOW offers a set of packages to simulate hydrologic stresses, inflows and outflows, to a groundwater system. Specifically, MODFLOW lacks a general method to process areally distributed recharge and discharge to groundwater. One solution would be to create a new package for MODFLOW. Alternatively, it is also possible to make the best use of existing code...
In deep space exploration, the information about the antenna pointing accuracy is required for prediction of the antenna performance in windy weather. The traditional design of large-diameter antenna generally uses finite element analysis method, it assumes a spatial correlated wind gust model which causes symmetrical wind loads, so the simulation results in the azimuth direction are always much smaller...
