摘要
小波分析是当前数学中一个迅速发展的新领域,在Matlab中,图像的增强、除噪、压缩是其应用领域中的一个方面.文中首先介绍了小波分析的历史与现状,然后详细地说明了当前小波分析在图像方面的各个应用领域和研究的意义,以及其研究工具Matlab组成和特点,从理论上讲解了小波变换的由来、定义和特点,在分析中所涉及到的连续小波变换、离散小波变换、二维小波变换.通过小波分析的理论研究,应用Matlab来实现了一般图像的压缩、除噪和增强,然后利用小波分析的工具箱打开图形接口方式,来实现相关小波分析的应用.由于小波分析在图像中有许多的优点,因此小波分析在各个应用领域也越来越广.
The issue of wavelet analysis is fast-developing in maths.The history and current situations of the wavelet analysis are introduced in the article,as well as its application and significance.Then the origin,definition and characteristics of the wavelet transform are stated.For continuous wavelet transform,discrete wavelet transform and two-dimensional wavelet transform,the wavelet analysis theory and Matlab are taken to achieve image compression,denoising and enhancement.The wavelet analysis toolbox is adopted to open graphics interface to realize the relevant application.Owning many advantages in the field of image compressing,wavelet analysis is being used in more and more areas.
