介绍一种Haar小波离散化消噪方法,并应用该方法进行信号和图像消噪处理.首先将信号或图像用该方法实现计算机的离散化抽样取点,然后结合小波阈值方对含噪信号或图像用Haar小波作消噪处理,并进行离散平滑,实现连续小波离散化处理.该方法对信号和图像的消噪处理的效果好,具有广泛应用的价值.
This paper presents denoising for Haar wavelet to process the signal and image denoising. The denoising method is used to realize the signal and image dispersed in the computer before removing the noises with the wavelet threshold. As a result,the method proves effective and practical in terms of the signal and image denoising.
