Obviously, the dynamic threshold is to use quasi-peak level that, while the signal to noiseratio is expressed with the quasi-average levels, and the difference is obvious in.
显见，动态阈是用准峰值电平表示，而信噪比则是用准平均值电平表示的，两者的区别是显而易见的了。

Compared with the traditional de-nosing methods by threshold value and translation invariance, the algorithm increases the signaltonoiseratio.
与传统的阈值去噪法和基于平移不变量的去噪算法相比，该算法提高了信噪比。

The variable relationship between the threshold of the extrapolation and its correspondent Peak of the Signal-to-NoiseRatio (PSNR) in the Wavelet Bi-linear Interpolation Algorithm is deeply analyzed.
