摘    要:在Xu和Witkin提出的小波空域去噪方法的基础上,结合小波软阈值去噪方法,提出了一种改进的小波空域相关去噪法。它具有空域相关法的优点,同时克服了空域相关法的缺点,对信号中的噪声进行了最大限度的抑制而又保留了信号的主要细节。实验证明此方法是有效的。

关 键 词:小波变换  空域相关  软阈值

Abstract:an improved wavelet denoising method is presented based on Xu and Witkin's spatial correlation filtering and combined with the wavelet soft threshold Denoising method. It has the advantage of spatial correlation filtering method, meanwhile it effectively overcomes the shortcomings .the new method mostly retain the main details of the signal while getting rid of noise. Experiment proved that this method is effective.
Keywords:wavelet transform  spatial correlation filtering  soft threshold
