代码说明:

提出了一种基于 Renyi 熵的阈值分割新方法。该方法首先计算代表目标和代表背景的熵值,然后求出两熵之和以及两熵之差的绝对值,最佳阈值对应于两者比值的最大值。Renyi 熵比传统的 Shannon 熵多了一个参数,此参数使得 Renyi 熵能够更灵活地处理多种类型的图像。按照本文方法进行实验,结果显示该算法比传统的 Shannon 熵方法更有效。

    说明:   倒立摆系统是研究控制理论的实验平台,它的行为与火箭飞行以及两足机器人行走有很大相似性,因而对其研究具有重大的理论和实践意义,一直是控制界关注的焦点。以直线单级倒立摆作为研究对象,采用最优控制策略实现对其平衡控制,进行仿真实验设计。(Inverted pendulum control theory is to study the experimental platform, its behavior and the rocket s flight and walking biped robot is very similar, and thus their study is of great theoretical and practical significance, has been the focus of attention control.
