A new speech enhancement method based on multitaper spectrum method and wavelet thresholding is proposed so that a noisy speech power spectrum is obtained.

It also analyzes for four models how the bias and variance of the multitaper spectrum are affected by the tapers number and estimation noise removal via wavelet thresholding,and further compares them with those of periodograms.

In theory of estimation with wavelet thresholding, the threshold adapting data can be cal- culated by minimum estimation of risk to improve the SNR of estimation.

A new multi-scale edge detection is proposed,in which we replace Gaussian filter in adaptive multi-scale edge detection with rotationally invariant wavelet shrinkage,and the filter scale set is determined by sampling exponentially,not by equidistantly.

Chambolle and Lucier proposed a new nonlinear scale space based on wavelet shrinkage.
