本书专为大学自动控制、机械电子、机械制造与自动化、电力电气、通信工程等专业大 学本科生、研究生、教师、科技工作者编写。本书力图将信号分析与处理、信号与系统、数字 信号处理、工程测试等有关教学内容和MATLAB语言紧密、有机地结合起来，使学生在 学习基础理论知识的同时学会应用MATLAB，在学习应用MATLAB的同时，加深对基 础知识的理解，增强学生的计算机应用能力，提高教学效果。本书编入大量MATI‘AB应 用程序，每章也有一定的数量习题，供读者能尽快掌握MATLAB的编程技巧。(This book is designed for the University of automatic control, mechanical, electronic, mechanical manufacturing and automation, electrical power, communications, engineering and other professional undergraduates, graduate students, teachers, scientists and write. This book seeks to signal analysis and processing, signals and systems, digital signal processing, engineering, testing and other relevant teaching content and MATLAB language closely, organically combine to make the students learn basic theoretical knowledge at the same time learn to use MATLAB, MATLAB in learning applications at the same time, deepen their understanding of the basics, enhance their computer skills to improve teaching effectiveness. Incorporated into the book a lot MATI' AB applications, each chapter there is a certain number of exercises for the reader can quickly grasp the MATLAB programming skills.)

不使用matlab库函数,实现图像的直方图均衡化,并且显示灰度变化的函数曲线(Do not use library functions to achieve the image histogram equalization)

说明：   使用二分法对样本集进行剪辑，剪辑法的思想，就是将样本集分成训练集与考试集， 利用训练集样本对考试集的样本进行分类（使用近邻法），如果考试集中某个样本分类错误的话，将这个样本删除。在该函数中，使用最近邻法，只进行一次剪辑（遍历完考试集中的样本以后退出）。还有一种重复剪辑法（适用于样本比较多的情况），把样本随机分为多个样本集，将相邻的两个样本前一个作为考试集，后一个作为训练集，调用二分剪辑。所有的样本子集剪辑完毕以后，在递归调用，直到没有样本被剪辑掉,没得讲，重复剪辑的效果肯定好一些。 (The sample sets using the dichotomy of the clips, editing law idea is to sample set into training set and test set, using the training set samples to the test set of samples (using the nearest neighbor algorithm), if the examination focused on a sample of classification error then delete this sample. In the function, use the nearest neighbor method, only once clips (focused on a sample of traversal finished after the exit exam). There is also a repeat clip method (samples are more applicable to the case), the samples were randomly divided into multiple sample set, the two adjacent samples of the former one as a test set, the latter one as a training set, call the two sub-clips. All the samples were a subset of the clips after they have finished, in the recursive call, until there are no samples were clip out, did not have to say that the effect of repeated clips definitely better.)
