As for the stable stochastic noise component linearly superposed on the median series, it is smoothed by means of the default soft threshold wavelet de-noising.
对线性叠加在中值系列中的平稳随机噪声，用默认软阈值小波消噪平滑中值序列中的随机噪声分量。
In order to remove this phenomenon, we consider the cycle spinning method based on threshold wavelet and then use the coefficient magnify to remove the signal noise.
为了去除这种现象，考虑在阈值法的基础上对信号进行循环平移，然后再对平移后阈值上的系数进行放大，对信号进行消噪处理。
Besides the high coding efficiency, the improved block-based adaptive threshold wavelet embedded coding algorithm preserves the properties of the SPECK and has high coding efficiency.
改进的分块自适应阈值算法不仅保留了原算法的优点，而且具有较高的编码效率。
