跳变点 meaning in English
tripoint
Examples
- It is well known that the wavelet liner approximation ( i . e , truncating the high frequencies ) can be approximate smooth singals very efficiently . however , for example , piecewise continous signals with large jump in signal value or in its derivatives , standard wavelet linear approximation techniques cannot achieve similar results for signals which are not smooth . to overcome these problems within the standard wavelet transform framework , the paper proposed the double adaptive wavelet transforms
众所周知，小波的线性近似(只用低频系数而不采用高频系数进行重构的方法称为线性近似)能非常有效的近似初始的光滑信号。然而对于非光滑信号，例如具有跳变点的分段连续信号，标准小波的线性近似就不能获得如光滑函数那样好的结果。
