This paper studies the mean square and almost sure consensus of discrete-time linear multi-agent systems with communication noises under Markovian switching topologies. By a sophisticated stochastic-approximation type protocol, the closed-loop dynamics of this linear multi-agent system can be transformed into a discrete-time first-order integral multi-agent system. It is proved that if all roots of...
By combining three-frame-difference method with background subtraction method, an approach is proposed for rapid detection and identification of moving targets. First the background frame is achieved after decoding frame operation on video which is collected by the robotic fish platform and made into gray-level. Then the threshold determined by the OTSU algorithm is employed to transform them into...
