在MATLAB环境下基于小波变换的图像去噪
Wavelet Transform In image De-noising using MATLAB
图像消噪是信号处理中的一个经典问题，传统的消噪方法多采用平均或线性方法进行，但是其消噪效果不好，随着小波理论的不断完善，它以自身良好的时频特性在图像消噪领域受到越来越多的关注，本文将以MATLAB为平台介绍以小波变换去除图像噪声的基本方法，并且在MATLAB中小波分析工具箱所提供的GUI上分析和验证滤波效果。 关键词：MATLAB,小波变换，图像去噪，GUI
Image de-noising is a classic problem in signal processing. the traditional denoising used the average or linear methods, but ite effect isn’t ideal.With the constant improvement of wavelet theory and its good time-frequency characteristics in the field of image de-noising it has attracted more and more attention, this article will introduce methods of using wavelet transform as the basic methods to remove image noise on MATLAB, and verify effects of the analysis and filtering in the GUI provided by MATLAB wavelet analysis’s toolbox.
