The original image, the noisy image, and the LL subbands of first level analysis using different wavelets. (a) The original image (238×211 pixels), (b) the noisy image, (c) the LL subband (119×96 pixels) decomposed using “bior3.9”, (d) the LL subband decomposed using the wavelet in Table1, (e) the pixels in (c) whose intensities are smaller than 0.4Imax are set as Imin, (f) the pixels (d) whose intensities are smaller than 0.4Imax are set as Imin, where Imax and Imin are the maximum and minimum of each image, respectively.
