摘要
A complete adaptive wavelet based de-noising method was presented. By giving the noise power threshold, proposing the distinctive coefficient COF and threshold coefficient th(m) and modifying the edge extraction order, we made the spatially selective noise filtration efficient. An estimation of noise level was also given here. The simulations show that the method can keep edges well while removing noise greatly.
