应用小波分析对图像进行降噪处理

摘要

对传统傅里叶变换与小波变换进行理论分析比较,运用小波分析中小波变换具有对信号的自适应特性可以消除实际信号噪声中的高频成分,通过使用Matlab-6.51中的Wavelet工具箱可实现对图片的降噪操作,最终达到降噪效果.%Analysis and comparison of the traditional theory of Fourier transform and wavelet transform,the wavelet analysis wavelet transform with adaptive characteristics of the signal can eliminate the high frequency components of the actual signal in noise,by using the Matlab-6.51 toolbox of Wavelet can reduce the noise on the image,finally achieve noise reduction effect.
