Attitude jitter is a common problem for high-resolution earth-observation satellites and can diminish the geo-positioning and mapping performance of observed images. It is especially necessary to address this problem when high-performance attitude measurements are unavailable. Therefore, an attitude jitter correction method for multispectral parallax imagery that utilizes the compressive-sensing technology...
A wireless sensor network is a self-organizing network which is composed of a large number of intelligent sensor nodes. The network topology is also changing with the residual energy of sensors. And the tree topology is an important and special one in sensor network. For reliability measure, it is important to find more reliable tree topology in the same class. In this paper, a new reliability measure...
Through analyzing the factors influencing BBD ball mill load and the measure characteristics, a BBD ball mill load measure method, based on rough set and neural networks information fusion, was proposed. A group of neural networks were constructed for material measure according to the relative reductions, which was feature-level information fusion. Then using the attribute significance determining...
For solving the problem in space object passive tracking with too short arcs acquired in space-based optical surveillance mission, the concepts of the attributable and the admissible region are introduced. And a triangulation subdivision and iterative searching method is put forward based on the triangulation node sorting by the cost function values. Simulation results indicate that this new method...
