matlab图像处理实例详解chap5——图像增强技术(matlab image processing example explanation chap5- image enhancement technology)

The purpose of this tutorial is to gain familiarity with MATLAB’s Image Processing Toolbox. This tutorial does not contain all of the functions available in MATLAB. It is very useful to go to HelpMATLAB Help in the MATLAB window if you have any questions not answered by this tutorial. Many of the examples in this tutorial are modified versions of MATLAB’s help examples. The help tool is especially useful in image processing applications, since there are numerous filter examples.

本代码实现基于Retinex理论的三种方法，分别为单尺度Retinex，多尺度Retinex，以及自商图像方法。直接运行每个文件夹下的test文件就可以得到对应的方法的处理结果。(This code implements three methods based on Retinex theory, respectively, for the single-scale Retinex, the multiscale Retinex, as well as self-quotient image method. The test file can be run directly under each folder corresponds to the method of processing results.)

自治系统Poincare映射的计算方法，附有程序以及算例。运行庞加莱里面的“zhixing.m”文件即可。(Autonomous system Poincare mapping method of calculation with procedures and examples are given. Run Poincaré inside zhixing.m files.)

风力发电中的风力模型 在MATLAB中的模型 很有用哦(Wind power in the wind model in MATLAB useful model in Oh)

matlab一百例，有详细的程序讲解，很有用的资料(matlab one hundred cases, explain the procedures detailed, useful information)

灰色系统的MATLAB程序：用于实现灰色预测，适合初学者。(Gray system MATLAB program: to achieve gray prediction for beginners.)

this is the histogram for color image
