LL subbands of first level analysis using different waThe original image and thevelets. (a) The original image (160×160 pixels), (b) the LL subband (80×80 pixels) decomposed using “bior3.9”, whose pixel intensities are smaller than 0.55Imax are set as Imin, (c) the LL subband (80×80 pixels) decomposed using the wavelet in Table1, whose pixel intensities are smaller than 0.55Imax are set as Imin.
