The idea of thresholding,then,is to set to zero all coefficients that are less than a particular threshold.These coefficients are used in an inverse wavelet transformation to reconstruct the data set.The technique is a significant step forward in handling noisy data because the denoising is carried out without smoothing out the sharp structures.The result is cleaned-up signal that still shows important details.

閾值方法的思想是把所有小于一個(gè)閾值的系數(shù)都置0,這些系數(shù)用在重建數(shù)據(jù)集合的逆小波變換中.該方法是處理噪聲數(shù)據(jù)的一個(gè)巨大進(jìn)步,因?yàn)槿ピ氩恍枰鸭怃J的數(shù)據(jù)進(jìn)行平滑處理.結(jié)果就是經(jīng)過處理的信號(hào)仍然具有重要的細(xì)節(jié)....
