Wavelet filter hard-thresholding

The hard-thresholding filter, fjj, selects wavelet coefficients that exceed a certain threshold and sets the others to zero ... [Pg.132]

The soft-thresholding filter, Fl, is similar to the hard-thresholding filter, but it also shrinks the wavelet coefficients above the threshold,... [Pg.132]
