The efficiency of a structural noise reduction has been evaluated by enhancement of the signal-to-noise ?doi=&rep=rep1&type=pdf. The more prosaic term “noise reduction” has been used by Lu et al. [31]. We propose here a formal interpretation of the term “de- noising” and show how wavelet transforms may be used to optimally “de-noise’’ in this interpretation.

Moreover, this “de- noising”   Indeed, thresholding the wavelet coefficients is the most straightforward way of distinguishing information from noise in the wavelet domain. In this Letter, the optimal threshold value is determined by minimising Stein's unbiased risk estimator (SURE) [ 23 ] called SureShrink and was proposed by Donoho and Johnstone [ 24 ].

In standard wavelet thresholding based noise reduction methods, the threshold at certain scale is a constant for all wavelet coefficients at this scale. 2.
