近似眾數
英文
approximate mode-
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
眾所周知，小波的線性近似（只用低頻系數而不採用高頻系數進行重構的方法稱為線性近似）能非常有效的近似初始的光滑信號。然而對于非光滑信號，例如具有跳變點的分段連續信號，標準小波的線性近似就不能獲得如光滑函數那樣好的結果。
