摘要
小波图像去噪已经成为目前图像去噪的主要方法之一,在分析了小波变换的基本理论和小波变换的多尺度分析基础上,根据多尺度小波变换的多分辨特性,提出了过抽样M通道小波变换去噪方法,并将此方法用于星图降噪处理中,收到良好的效果.
Wavelet image denoising has been well acknowledged as an important method of image denoising. The basic theory and the multi-scaling of the wavelet transform are analysed in this paper. According to the characteristics of the multi-scaling analysis, the method of oversampling M-channels based on the multi-scaling of the wavelet transforms is presented.
