在很多图像处理的过程中，需要判别一个图像的清晰度，和图像分割结果的优劣，于是就引出了信息熵的概念，绝大多数时候，它都被用来作为评价图像的一个量化标准。(In many image processing processes, it is necessary to distinguish the clarity of an image and the result of image segmentation, so the concept of information entropy is introduced. Most of the time, it is used as a quantitative standard to evaluate the image.)

说明：  文档中的matlab源代码主要是针对单回路液位控制系统的PID控制实现，内有simulink原理图(Matlab source code in the document is mainly for single-loop PID control of water level control system to achieve, within the simulink diagram)
