实现高通和低通滤波，主要是先进行傅里叶变换，然后对频谱图滤波后再逆变换得到滤波之后的图片(High-pass and low pass filter, mainly the first Fourier transform, frequency spectrum and then inverse transform filter and filtered image)

模糊聚类程序包，fcm、kmeans等很详细(Fuzzy clustering packages, fcm, kmeans and so very detailed)

LEACH (Low Energy Adaptive Clustering Hierarchy) is designed for sensor networks where an end-user wants to remotely monitor the environment. In such a situation, the data from the individual nodes must be sent to a central base station, often located far from the sensor network, through which the end-user can access the data.

这是一本有关MATLAB的参考书，适合于使用MATLAB或正在打算使用MATLAB的读者。本书另辟蹊径可以借助或不借助MATLAB随带的文档资料让读者自学MATLAB。 作为编程语言和可视化工具,MATLAB具有丰富的一系列功能,可解决工程、科学计算和数学学科中许多问题。本书的基本目的是通过向读者展示如何有效地使用这些功能来帮助读者增强工作能力。由于MATLAB交互式的性质,书中内容以举例方式来描述。在读者阅读本书的同时, 这些例子可以通过运行MATLAB而再现。 (This is a reference book on MATLAB, suitable for the use of MATLAB or is intended to use MATLAB readers. Another way this book can make use of, or without the aid of MATLAB documentation that came with the reader learning MATLAB. As a programming language and visualization tools, MATLAB has a rich range of functions, solve engineering, scientific computing and mathematics disciplines, many problems. The basic purpose of this book by showing the reader how to effectively use these features to help readers enhance the ability to work. Since MATLAB interactive nature of the book by way of example to describe the content. The reader to read this book at the same time, these examples by running the MATLAB and reproduction.)
