Judging whether a point is in a quadrangle (rectangle, paralleled-gram and polygon) is a problem met frequently in simulation. It will affect the precision and fidelity of simulation directly, especia
Local visual attention mechanism (LVAM) is firstly presented and combined with bottom-up visual attention mechanism (VAM) to form a unified visual attention framework, based on which a novel infrared
The analysis method of weapon system was restricted to single equipment or single weapon system at the present time. This paper mainly solves this problem from the viewpoint of weapon systems and hier
In this paper, we propose a new method based on qualitative simulation to construct phase portrait for nonlinear dynamic system. We firstly improve the QSIM algorithm, which is the most widely used in
A comprehensive survey of qualitative representations in cognitive maps is provided in this paper from spatial cognition perspective. The necessity of qualitative representation for robot navigation a
